Types of Reference Materials
Subject Specific Reference Sources

Explanation

This page contains definitions of and examples of different types of reference sources including almanacs, atlases, bibliographies, biographies, chronologies, dictionaries, directories, encyclopedias, handbooks, and indexes.

Almanacs are not usually used for extensive research , but are good for looking up specific facts, statistics, tables and lists about people, places, events, countries, organizations, zip codes, and popular culture such as sports and entertainment. Generally, almanacs cover a broad period of time, while Yearbooks, which contain similar information, only cover a given year.

Atlases contain an organized group of pictorial or illustrated political, cultural, physical, road, and/or thematic maps. Atlases may be organized around a specific subject, theme, or geographic area.

Bibliographies

Bibliographies compile comprehensive lists of resources that share one or more common attributes about a particular subject, person, geographical area, etc. Some bibliographies also briefly describe the resources that are listed. One should consult a bibliography when they want citations that will guide them to specific resources.

Biographies

Biographies contain information about people, both living and deceased - they can contain brief summaries of data about individuals, contain lists of citations of resources about a person, or be full length books detailing the life of one particular person. Biographies may cover general important figures, or may be organized thematically/geographically, etc. One would use a biography to look up facts or detailed information about a person or group of people.

Chronologies / Timelines

Chronologies and timelines summarize the advancement of an event or happening by supplying brief milestones in the progression of the event. The summaries will be presented day-by-day, year-by-year, or by another chronological breakdown.

Dictionaries

Standard dictionaries give an alphabetical list of words and their definitions, but there are several useful variations also classified as dictionaries. Thesauri contain synonyms and antonyms (opposites) but usually don't define the words. There are also dialect and slang dictionaries, dictionaries of abbreviations and acronyms, dictionaries of quotations, and picture dictionaries. Dictionaries can be unabridged (general) or can be thematically organized in some way.

Directories

Directories contain an organized list of people and/or organizations, and help one to find information such as addresses, phone numbers, and email addresses, etc. for the organizations or people included within the scope of that directory.

Encyclopedias

Encyclopedias contain full coverage of information about an area of knowledge. They can be general or can cover a specific subject, and contain alphabetically organized entries with varying detail. These are great starting points for fact-finding, getting background topic information, learning of key events and individuals, or starting a research project. Below is a major general encyclopedia. See Best Practices on this guides Home page to pinpoint valuable subject-specific encyclopedias.

Britannica ACADEMIC This link opens in a new window Encyclopedia Britannica online includes topic overviews, biographies, word and concept definitions, a world atlas, historical timelines, quotations, illustrations, photos, videos, links to relevant articles and websites, primary sources, and the World Data Analyst.

Handbooks / Manuals

A handbook contains facts about a specific subject or instructions that can be used to accomplish something. A handbook can come in several forms, such as a manual for completing tasks, or a guidebook providing information about a subject, region, etc. (such as a travel guidebook). Handbooks are often designed for quick consultation and easy portability.

Indexes are compilations on information, generally arranged either alphabetically or numerically, that indicate the location of related information either within or outside of the same resource.

References Writing Guide

Here are some general guidelines for writing references:

Follow the citation style guidelines: Different disciplines and journals may require different citation styles (e.g., APA, MLA, Chicago). It is important to follow the specific guidelines for the citation style required.
Include all necessary information : Each citation should include enough information for readers to locate the source. For example, a journal article citation should include the author(s), title of the article, journal title, volume number, issue number, page numbers, and publication year.
Use proper formatting: Citation styles typically have specific formatting requirements for different types of sources. Make sure to follow the proper formatting for each citation.
Order citations alphabetically: If listing multiple sources, they should be listed alphabetically by the author’s last name.
Be consistent: Use the same citation style throughout the entire paper or project.
Check for accuracy: Double-check all citations to ensure accuracy, including correct spelling of author names and publication information.
Use reputable sources: When selecting sources to cite, choose reputable and authoritative sources. Avoid sources that are biased or unreliable.
Include all sources: Make sure to include all sources used in the research, including those that were not directly quoted but still informed the work.
Use online tools : There are online tools available (e.g., citation generators) that can help with formatting and organizing references.

Purpose of References in Research

References in research serve several purposes:

To give credit to the original authors or sources of information used in the research. It is important to acknowledge the work of others and avoid plagiarism.
To provide evidence for the claims made in the research. References can support the arguments, hypotheses, or conclusions presented in the research by citing relevant studies, data, or theories.
To allow readers to find and verify the sources used in the research. References provide the necessary information for readers to locate and access the sources cited in the research, which allows them to evaluate the quality and reliability of the information presented.
To situate the research within the broader context of the field. References can show how the research builds on or contributes to the existing body of knowledge, and can help readers to identify gaps in the literature that the research seeks to address.

Importance of References in Research

References play an important role in research for several reasons:

Credibility : By citing authoritative sources, references lend credibility to the research and its claims. They provide evidence that the research is based on a sound foundation of knowledge and has been carefully researched.
Avoidance of Plagiarism : References help researchers avoid plagiarism by giving credit to the original authors or sources of information. This is important for ethical reasons and also to avoid legal repercussions.
Reproducibility : References allow others to reproduce the research by providing detailed information on the sources used. This is important for verification of the research and for others to build on the work.
Context : References provide context for the research by situating it within the broader body of knowledge in the field. They help researchers to understand where their work fits in and how it builds on or contributes to existing knowledge.
Evaluation : References provide a means for others to evaluate the research by allowing them to assess the quality and reliability of the sources used.

Advantages of References in Research

There are several advantages of including references in research:

Acknowledgment of Sources: Including references gives credit to the authors or sources of information used in the research. This is important to acknowledge the original work and avoid plagiarism.
Evidence and Support : References can provide evidence to support the arguments, hypotheses, or conclusions presented in the research. This can add credibility and strength to the research.
Reproducibility : References provide the necessary information for others to reproduce the research. This is important for the verification of the research and for others to build on the work.
Context : References can help to situate the research within the broader body of knowledge in the field. This helps researchers to understand where their work fits in and how it builds on or contributes to existing knowledge.
Evaluation : Including references allows others to evaluate the research by providing a means to assess the quality and reliability of the sources used.
Ongoing Conversation: References allow researchers to engage in ongoing conversations and debates within their fields. They can show how the research builds on or contributes to the existing body of knowledge.

The author does an incredible job in explaining the research process, from choosing a research question to how to search for sources (and citing those sources), and more. There are relevant self-check quizzes throughout the book to check for understanding, along with other supplemental resources. As the book was published through The Ohio State University, some of the sources are only available to OSU students, but the author makes it clear when this is the case.

Content Accuracy rating: 5

The author did an excellent job with the accuracy of the book, Two specific examples that stood out: taking care to mention that Wikipedia is a great as a starting point, but not as an endpoint for research. Lowry also clearly explained that educational use did not automatically mean fair use, which seems to be an issue with students and faculty alike.

Relevance/Longevity rating: 5

The book should remain relevant in years to come, as academic research seems to follow the same basic pattern. The only issue would be if The Ohio State University changes the links used in the book, although I expect these to be easy to update. The book would still be able to be used without the supplemental links though.

Clarity rating: 5

The book seems to be targeting an introductory audience. Lowry does a great job of breaking down the jargon of academic research into plain English for the beginning researcher.

Consistency rating: 5

I thought the author used approprate terminology for a student learning about academic research.

Modularity rating: 5

The book is designed into specific chapters for the different aspects of choosing a source. While there are specific sections devoted to The Ohio State University library, I would not expect to have any trouble assigning the other chapters in my courses.

Organization/Structure/Flow rating: 5

The author started at the beginning, with how to design a research question before going into choosing a source, which gave good background knowledge.

Interface rating: 5

The contents of the book were clean and crisp. No distortions were noted. Navigation from the table of contents was easy.

Grammatical Errors rating: 5

No grammatical errors were noted.

Cultural Relevance rating: 5

Nothing offensive was in the book.

I have a difficult time in getting beginning graduate student to understand the different types of sources and fair use. I think using most chapters of this book would help a great deal in that comprehension.

This student friendly overview of academic research, including a strong focus on information literacy, covers many of the salient points that college level writing and writing for research classes curricula contain, making it a strong choice as a comprehensive and useful overview. Chapters include enough depth of coverage to make the leap from information to practice for students; self-directed activities are provided to check knowledge, work through concept applications, and offer more specifics. The book provides an easy-to-navigate Table of Contents, but an Index and Glossary do not seem to be available.

Content Accuracy rating: 4

Some errors appear that a thorough proofread would catch. Some resources may need to be updated since information practices and modes change so quickly; some references and links direct students to OSU information that would not apply to all readers.

Relevance/Longevity rating: 4

The book’s topic – academic research – necessarily demands constant updating given our fast-changing digital landscape and the shifting paradigms we are witnessing for locating and evaluating information in our times. Resources can become obsolete fairly quickly in this environment. The book’s content is largely up-to-date, though a thorough review of linked resources, perhaps annually, would be beneficial. For instance, a video on RSS mentioned a Google feature that looks to be no longer available, though finding alternatives proves simple when searched online. The book’s organization makes updating or replacing linked resources easy, so keeping the content relevant would be straightforward with regular review.

Content is presented in a style engaging for students, using the “you” pronoun address to walk readers through a thinking process that applies and links ideas to practice; this effective approach is used for many of the book’s concepts. The writing strikes a good stylistic balance between engaging the student reader and informing/challenging that same reader by modeling research brainstorming or methods. The style seems appropriate for college level readers and college level curricula. The topic of academic research does include some technical terms at times, but the book’s approach is to define and explain such terms a part of its content.

Stylistically and organizationally, the content is consistent and easy-to-follow. A user begins to anticipate knowledge check activities or “try it out” activities at particular points in each section. The knowledge check quizzes, which are simplified multiple choice questions, seem at odds with the highly contextualized concept explanations in much of the book’s prose; perhaps a different approach to knowledge check quizzing, which as an element can be helpful, would work better.

Modularity rating: 4

Headings and subheadings follow a logical organization and are easy to navigate in the book. Some sections do refer to—and link to—other book sections, but most would work as stand-alone modules. An instructor or course designer could pick and choose sections and adapt them for their own purposes. As a whole, the book remains self-referential to the context of a specific university, which limits the easy adaptation of the book, and perhaps even sections, for faculty and course designers at other educational institutions.

The book’s organization is easy to navigate and coheres with the overall focus on presenting academic research and information literacy in a way that invites students toward a practical and fuller understanding. Topic order makes sense and is organized via headings and subheadings well.

Overall, no significant navigation issues or interface distractions.

A few errors that look like typos remain in the book. Otherwise, grammatical errors are not an issue for readability.

Cultural Relevance rating: 4

A more nuanced and inclusive awareness of cultural relevance and diversity is worth considering for the book. The choice of some example topics, such as school shootings, might be distracting or traumatic for some student populations, while adding more examples that showcase interests or topics related to non-dominant cultural ideas would widen the sense of inclusivity throughout the book. Choices might be contingent on the demographics of the Ohio State University population, but more awareness of this aspect of the book might also make it more appealing as a resource for others to adapt

This text provides a well-balanced, research-driven approach to guiding students through the process of writing an academic research paper. Spelling mistakes, flaw grammar and usage, and factual errors are few and far between (as in I didn't find any during the course of this review).

Kinds of sources and the means of evaluating them are broad enough to be long-lasting, but the examples and other supporting details are timely and relevant.

This text uses student-friendly language and avoids jargon and other symptoms of academia run amok, while still maintaining high standards and expectations for students. Connections between the different stages of conducting research and developing an argument are well laid out and clear.

Terms associated with locating, evaluating, and incorporating a range of different kinds of sources are clear and consistent throughout the text.

The chapters do stand alone and I could image someone using bits and pieces or leaving out bits and pieces, but since the text is primarily focused on supporting the needs of a college research throughout the research process, it is hard to image much need for separating it into discrete modules. You could certainly rearrange the order of the chapters too if that worked better for your approach to teaching student research.

The flow of one chapter into the next is well-integrated and smooth. The order of the chapters

I had no issues with the interface; everything worked as expected.

Cultural Relevance rating: 3

The book does not go out of its way to make obviously inclusive examples. Increasing the cultural perspectives represented in the examples would enhance the overall value of this text.

Reviewed by Darci Adolf, Director of Library & Media Services, Oregon Coast Community College on 6/11/21

I found "Choosing and Using Sources" to be quite comprehensive and included the major areas that I cover in my LIB 101 Research skills class. In my class I like to cover each area of Eisenberg's Big6 Research model: Task definition, information seeking strategies, location and access, use of information, synthesis, and evaluation. I was pleased to find the subject of synthesis covered under the writing chapter-- many research textbooks leave this out. I did not find anything that talked about Evaluation of the process and product. Also, I would've liked to have seen social justice and equity issues in information publishing and access addressed as a chapter or portion of a chapter. The textbook has a great Table of Contents, but no index.

This textbook seems to contain accurate and error-free content. I spot-checked most of the chapters and didn't find anything I didn't believe to be true, and links weren't broken. Because this book is mostly factual in nature, there aren't areas where an author's opinion was used over facts, and opinions seem to be be appropriate and unbiased. For example, the author remarks on the use of blogs in research: "Blogs – Frequently updated websites that do not necessarily require extensive technical skills and can be published by virtually anyone for no cost to themselves other than the time they devote to content creation." This is a wide-held belief among librarians.

The content appeared to be up-to-date throughout the book. The area that might change the quickest is the types of sources, Chapter 2 in the book. They did a good job including an overview of all of the major source types and should stay relevant for a good period of time. Because they've listed these source types in a single chapter, updates to the text should be fairly straight forward and easy to do without disturbing much of the rest of the book.

Clarity rating: 4

The text was clear to me, a seasoned librarian. But I think there were terms used throughout the textbook that might not be familiar to a student first starting out in library research. So I would add some clarification around some of the language if I were using this textbook for a lower-level class. For example: There are several types of specialized databases listed including: Bibliographic, Full-text, Multimedia, etc. Many first year students wouldn't know those terms, or others such as "circulation, World-cat, discharge, InterLibrary Loan" and so forth.

The text was consistent throughout in terms of terminology and the overall frame. As I mentioned previously, some of the terms might need to be defined for the first-year student, either in-text or in a separate glossary. The framework is well-done, with clear chapters and sections--it was definitely written by those who teach research at the college level.

The textbook has 13 chapters that are again sub-divided into six or more sub-topics. This makes it very easy for an instructor to pick and choose which topics to cover. The thirteen broader subjects makes it easy to use the entire textbook for a term-- or just choose the pieces you want to use. For example, I would use the "Ethical Use and Citing Sources" chapter if I were doing a one-shot in a classroom, but might choose to use most of the chapters for an online class.

The structure was easy to follow. If I were setting it up myself, I'd probably combine the chapters on Ethical Use of Sources (Ethical Use and Citing Sources, Why Cite Sources, and Challenges in Citing Sources) with the chapter on "How to Cite Sources," but it's easier to have them separate and combine them for a class than to have a big block of text that would make it difficult to work through.

The textbook online version was done in Wordpress, and was easy to view and navigate. There were several other choices for students, including a PDF that could be viewed off line. There were charts, graphs, and links throughout that added to the content, but not so much as to be distracting. Any visuals were simple and enough white space was left as to not overwhelm, with colors that were contrasting visually.

I spot-checked throughout the text in each chapter and did not find any grammatical errors.

The textbook seemed to be inclusive of all races, ethnicities, and backgrounds.

Ohio State University has included a lot of links to their own pages, handouts, and resources that would need to be changed or omitted by a new user. For example, they have a handout from the OSU Writing Center, and they link to the OSU World Cat platform. These would need to be changed by the adopter.

Reviewed by Kaia Henrickson, Assistant Professor of Library & Information Science, Information Literacy Librarian, University of Alaska, Southeast on 11/4/20, updated 12/16/20

This text does a good job highlighting the steps in the research process, from formulating a strong research question, to finding and evaluating sources, to incorporating ideas from research into writing, and finally, to citing and using sources properly. Each chapter can stand on its own as useful content for a research-based course, or the entire text could be used to walk students through the entire research and writing process. Based on tutorials created for Ohio State University Libraries, some sections, like Chapter 5 on search tools as well as some of the activities, are fairly specific to OSU. Still, much of the text and many of the activities are applicable to all student researchers. This would be a great base text for someone who wanted to remix and add in information from their own university library and student service supports to replace the OSU-focused sections.

The material is accurate overall.

Text content, as well as videos and activities, are fairly current. Sections are small, so making updates should be fairly easy.

While the text is generally clear, there are sections that are a bit cumbersome or wordy. The Evaluating Sources section, especially, seems overly complicated.

References and links to other helpful sections within the text are appropriate and useful. Key concepts and ideas are repeated and built upon as the text progresses.

Each chapter is divided into manageable sections, and there are few sections which require a lot of scrolling. Those that are longer are broken up by subheadings. Embedded video content, visuals, and boxes are used to break up the text for easier reading and more visual appeal.

The text clearly progresses through the steps in the research and writing process from start to finish, but it can also be accessed by section if a particular subtopic is all that is needed. Each chapter stands on its own, as well as being integrated into the whole.

Interface rating: 3

The web version of the text has no paragraph indents or lines of space between paragraphs, which makes it a bit difficult to read, especially when there are longer blocks of text. There are many videos included that only have automatically-created closed captions (and a few with no closed captions available at all). A few of the graphics are blurry, but most visual and audiovisual content is clear and easy to read. With some of the linked activities, it is unclear what to do when you have selected an incorrect answer, and there is not much feedback for students who answer questions incorrectly.

Grammatical Errors rating: 4

There are a few typos and other minor issues here and there in the text. Some of the linked activities have more significant errors.

The text is not culturally insensitive, but it also doesn't present much in the way of diversity in examples or ideas. In addition, there is a noticeable amount content that is focused on Ohio State University resources and students, and this may not be relevant for readers from other universities.

I will use this book for my undergraduate research course as it gives a very good introduction to research, from narrowing the topic to turning questions into hypotheses.

The book is very clear and provides graphs, links and videos for the reader to have additional information as needed.

Each chapter is organized similarly to the others and is written in the same easy-to-follow, technical-free language. It removes any inhibitions a reader might have.

Each chapter section has its own heading and link. The entire book could be assigned or sections of the book could be just as easily assigned. A drop-down table of contents menu allows the reader to move freely between topics.

This guide is beautifully organized for the beginning researcher but can easily be followed through the table of contents for students needed refreshers on particular elements of research.

I found no interface issues at all in navigating the book.

There were no grammatical errors in the text.

I believe the book would be welcomed by a diverse group of people. There is no insensitive language or use of poor examples in the book.

I really enjoyed the organization of the book and that the author takes the time to include links to additional information as well as videos for students who want to spend more time with a particular concept.

This information is presented in an unbiased way that informs on the topic rather than presenting a strong bias or slant toward a particular type of source (though, there is cultural bias—see review comments in “cultural” section). The text does provide details on what approaches might be more helpful in certain situations. This provides a balance of usefulness for students trying to determine which sources to use, while also not assigning value to some sources over others or create a hierarchy.

Relevance/Longevity rating: 3

The text demonstrates a current understanding around the topic of sources, taking into account the shift away from paper and toward digital sources. While overall this text should be useful for several years, there are some areas that may require updating (e.g. links, OSU policies or statements, specifics about various citation styles, software options available, copyright laws, etc.). Throughout the text, the authors do depend on examples that are specific to OSU (e.g. a section on “WorldCat@OSU”), and this might provide less useful for non-OSU students.

The text is written with simple language and explanations are given for more technical terminology (e.g. peer-reviewed, quantitative, qualitative, etc.).

Little specialized terminology is used throughout the text, however, the language and terminology used is consistent throughout. The format, structure, and approach the authors use, is also consistent throughout the text and forms a cohesive narrative.

The text is broken up by main topics and then within each topic, subtopics are provided to support the main topic. The length of each subtopic is fairly brief and examples are provided throughout with graphical separation for clarity. While the topics and subtopics support each other, each subtopic could be assigned individually and would maintain usefulness.

Organization/Structure/Flow rating: 4

Overall, the organization is logical and clear. There are a few topics that might be shifted in their order, but this is not a critical need. For instance, moving the information about copyright closer to the section on ethical use of sources might make sense, but does not overly disrupt the general flow of the text.

There are no significant issues. A fixed bar at the bottom of the screen allows for navigation to pages directly preceding and proceeding the current page and a clickable contents button at the top right side of the page allows further navigation between sections. Overall, visuals do not appear to be distorted, however, many of the visuals are quite large, taking up the majority of the screen, and could be reduced in size without losing effectiveness. Additionally, on pages 9 and 11, a graphic is presented that contains text that is too small to read. While it is not necessary to read the text in the visual in order to understand the lesson of the section, because it is provided, it would be reasonable to make this large enough to be legible.

The text seems to be free of any major grammatical errors.

This text is written from an academic, western cultural perspective that is relevant to the particular topic and audience (i.e. “A guide to academic research”), but does not take into other ontological or epistemological scholarly perspectives (e.g. testimonios or oral histories as significant sources). The visuals and examples do privilege the U.S. and mainstream cultures, such as through a photo of a White woman using her Mac computer in a library, a photo of a football team, an illustration with the U.S. flag in it, an example question of “How has NASA helped America,” an example opinion of “George Clooney is the sexiest actor alive,” etc. The text is not overtly insensitive or offensive, but it also does not appear to take up or address non-dominant perspectives and cultures in any substantive way.

The text is very comprehensive and covers all the necessary aspects of information literacy and student research. There is no index or glossary included, but terms are well explained within the text. The extensive coverage of topics, like types of sources and copyright, was thorough while not being so in-depth as to bore students. The activities, quizzes, and short videos reinforce the concepts covered in the chapters and add interest, however some quizzes would benefit from additional explanation as to why answers are right or wrong.

The content of the text seems to be accurate. Very minor spelling errors and a copy/paste duplicate. No apparent bias.

Content is up to date and relevant for students while being broad enough to be useful for a longer period of time. Updating information would be easy. The text contains a lot of hyperlinks that an instructor would need to stay on top of to keep the links current. In some cases the links were to very reliable sources that will remain stable for a long time (i.e. Purdue OWL) while others are more transient (i.e. YouTube videos).

In general the text is clear, including good explanations of terms and concepts. It contains very little jargon and the prose is accessible. In “The Details Are Tricky” section, the finer points of primary, secondary, or tertiary information could be confusing to students who are trying to comprehend the basics. The author’s inclusion of informative tables with sample responses as well as the blank template for students to use was helpful.

There is consistent use of terminology and layout throughout the text.

The book has good modularity, excellent graphics, and the text and/or activities can easily be used at the point of need in an information literacy class or one that is discipline specific. Chapters can be used individually or rearranged as needed.

Overall the organizational flow worked well, however the chapters on copyright and fair use might make more sense when grouped with the chapters on the ethical use of sources and how to cite sources.

The EPUB and web versions of the text are easy to navigate with a clickable table of contents and left/right arrow navigation at the bottom of each page. Other than some images that could be resized, the formatting lent itself to consistency throughout the text giving students a uniform experience. In some cases the URL links were just written text instead of hyperlinked which was a little inconsistent. Pleasant graphics added value, explained concepts, balanced out the text, and added visual interest. The inclusion of links that lead out to further explanations of concepts (i.e. the peer review process or how to read a scholarly article) are a nice addition.

There are no major grammatical errors that would be distracting to the reader.

The text is applicable to students in all disciplines, and there are no concerns about cultural relevance or insensitivity. The text is heavily OSU centric (i.e. referencing the OSU code of conduct and requiring students to log in to OSU resources for some activities and examples) and requires effort on the part of instructors at other institutions to make the necessary changes making the content applicable at their institution.

With modifications this text could be incorporated into a three credit information literacy course for undergraduates or into other disciplines. The fair use and copyright sections could be useful to instructors as well as students. Could easily integrate with the ACRL Framework. There is some great general information on writing and making an argument that are applicable across disciplines.

The text is divided in a way to teach across a course. While the text builds upon itself, many of the chapters stand alone well. I have skipped several chapters of the text and it has not caused any disruption with students.

Excellent organization. The text guides the reader step by step through the research process.

Interface rating: 4

The overall interface is strong. The images and charts are excellent, although the use of branded logos in some of the images may become dated.

No grammatical errors noted.

The text is focused on academic research practices for a North American context. While not culturally insensitive or offensive in any way, it does not take into consideration research practices of other cultures.

I use this text as a replacement of Booth et al.’s Craft of Research. Beside the benefits of being a open textbook, this text provides a more relevant guide to finding sources in the current academic environment.

This book includes all relevant information to help students choose appropriate sources for an academic research paper. It clearly defines different types of sources that can be used, and the difference between primary and secondary sources. It gives an overview of how to search various databases, and defines and describes boolean operators. The chapter on ethical uses of sources clearly defines plagiarism and how and when to cite so as to avoid plagiarizing. The chapter on copyright is an excellent addition; that information is not common in many texts related to academic writing. Each chapter contains extra activities students can work on independently to help with understanding and application of the material covered.

Overall, I found the book to be accurate. I did find one error in Chapter 7. In the section titled "Challenges in Citing Sources" the entry labeled "Running out of Time" was repeated. In regards to bias--I did not find the content to be biased; however, the majority of links where students could go to get extra information were connected to Ohio State University. The one notable exception were the links to the Perdue Online Writing Lab.

The content is up-to-date and relevant. Choosing and using sources for an academic paper has not changed much. What has changed is how to access and find the sources to choose and use. This book does a nice job of explaining how to find sources--databases, google scholar, and search engines. My only concern is the frequent suggestion to search Wikipedia. As an academic, I find this a little troubling. To the author's credit, they did not that one should not cite Wikipedia or use information from Wikipedia in an academic paper. I am not able to comment on ease of updating information, as that is a technical issue.

The book is written in clear, accessible language, with limited "jargon." At times I found the writing to be too simple, written more for high school students than college students. Definitions are provided for all relevant terms.

The book is internally consistent. It moves through the process of choosing and using sources in a linear fashion. However, to their credit, the authors note that writing an academic research paper is not always a linear process.

Each chapter is broken up into smaller units that cover a topic relevant to the chapter theme. Sections of this book could be assigned as individual assignments based on areas of difficultly students seem to be having. Alternatively, a professor could develop a class session or two around each of the chapters. These book seems to be very versatile; there are links to previous chapters that readers can click on to refresh their memories.

The topics in the text are presented in a logical and clear way. The book moves through each topic associated with choosing and using sources in sequence that most researchers would follow. The table of contents, with main headings and subtopics provide a step-by-step guide to help undergraduate students through the research process.

There are many links in throughout the book that students can click on to get more information or to practice skills. Navigation back to the main text is a little trickier. Sometimes, clicking on the back arrow will get the reader back to the page s/he was studying before clicking on the hyperlink. More often, however, the back arrow will take the reader back to the Table of Contents, or front cover of the book. Not all the links worked when I went through the book

I did not fine any grammatical or mechanical errors. I think the book is well-written and appropriate for high school students. I think the language may be too simplistic for most college students.

I did not come across anything that was culturally insensitive or offensive in any way.

I think this book is an excellent resource for high school students, and maybe college freshman who need help in choosing and using sources for an academic paper. The book is logical, gives an overview of the process and provides excellent examples and extra activities to enhance learning. I think it also could be used as a self-study guide.

This book is a great resource of all steps needed to be taken in an academic research process. The book's index clearly displays a suggested methodology to follow and makes it easier to comeback for the review of previous chapters. In general the book is easy to read and every time a new world or a particular terminology related to the topic comes up, it is clearly defined and put into context.

This book collects a series of methodologies that have been proven to be efficient when they are put into use during the process of academic research. These techniques are not only presented and described to the readers, they are also actively used in the various examples, pretty much in every chapter in the book. These techniques may not be the only way a person can start and develop a research process but they are certainly a clear and convenient way to do so for beginners. There may be complex terminology entered to the discussion which may slow down the reading process. However, this is effectively addressed by separated easy to access links; This provide more in detail definitions and exercises from a particular section.

This book is a guide that presents many particularities of research methods and techniques that have been used for long time. These methodologies have been proven to be very effective in academic research. This book not only collects many of these techniques but carefully relate them to new searching tools that are part of the communication era we live in nowadays. This was not the case just couple of decades ago. I anticipate long life to the methodologies presented in this text with years or decades before they could become obsolete. Within this context, the searching tools may keep changing but the methodologies that are used here could keep working efficiently; at least as a way to approach to a research process for an undergrad student.

The author uses a clear and easy way to understand the language and terminology that makes part of a research process. Without getting too deep into technical terminology the book marks clearly words that deserve more understanding and usually provides separate links which connects the reader with a deeper explanation. The text doesn't have very large paragraphs all around which to me allows readers to keep a good and dynamic paste. Links to previous discussed topics presents a quick way to review previous content without loosing the paste.

Consistency rating: 4

Through out the entire text it is consistent that at the beginning of every chapter there's a statement related to what the previous set of contents was, also in several parts of the book this first paragraph makes a point about how this relates to what it is about to be presented in that chapter. This is why several words allusive to the subject of research are reuse constantly in different chapters. This makes lots of sense to me as a way to keep the reader's familiarity with these terms which will also ended up increasing retentivity levels in the subject. Since the book is clearly broken down into steps they all seemed to be well placed in order to present a cohesive structure that guides the process of research.

Academic research it is a process that should be flexible by nature in many ways. Even though some parts of the process could be done simultaneously to others, this will definitely not apply to all of them. This book brings up an interesting way to order this process which even though may look rigid at times it tries to make sure that some parts are developed before others in the research. It is presented that way so that there's enough understanding of the bases before there can be any progression or even conclusions. This is mostly reflected in the techniques that are presented, where some of then have as their main job to detonate creative thinking. For example: the importance of the set of questions that are asked at the beginning is that the answers will be used mostly to clarify the end goals of a research.

This text is organized following a clear and efficient way to develop an academic research process. It is well distributed in chapters that are all connected to each other in one or other way. The book is efficient at establishing this connections, specially at the beginning and end of every chapter where there's mentioning of the previous and following topic's main ideas. This helps readers to keep track with the overall content.

This book presents an excellent graphic approach to expose its content. The electronic version has the really nice feature of having the index accessible at any point of the reading process. This text is full of links that are either deeper explanations of a particular topic or a set of exercises that are directly related to what the reader is learning. If the idea was to present the information in a format that doesn't look congested to the eyes and that it is not distracting the reader from the important ideas, the editors made an excellent job. This book can't be easier to read, follow through and understand.

Besides a couple of punctuation spaces here and then I was not able to perceive any major grammatical errors. The book is well written all around. Punctuation is pretty much excellent and its composition keeps the reader in track with the content effectible.

Particularly the topics used as examples were very diverse in therms of gender allusion, cultural backgrounds and specialized fields. Research is a process that apply to all disciplines and the professionals working in them. This makes the research process a particularly broad one. The book makes efforts to present this idea by using numerous examples that connect with different segments of the population at numerous levels.

This books is an excellent tool available to anyone who wishes to start a serious research process in almost any particular professional area or field, even amateur researchers can benefit from its content. The book was written to merge the topic content with a series of exercises, tests and examples using a cohesive testing dynamic that helps to increase retention. This dynamic becomes the most efficient way to understand what it takes to start a professional research. The steps to follow the process are laid out clearly in this guide and the important things that need to be taking in account during the research process are highlighted and deconstructed to obtain a deeper overall understanding by the reader or researcher. The fact that the reader is being quizzed constantly during the entire book generates a stronger connection with the important subjects and a good way to evaluate the reader's understanding in real time as well. Highly recommended to undergrad and graduate students and perhaps even amateur researchers becoming familiar with the process of research as well.

Choosing and Using Sources does a very good job of covering the topic of Academic Research. Each chapter focuses on an aspect of the research process and thoroughly covers the content with easy to read text and examples/activities for student practice. Most importantly first-year students through seniors should find the content informative and presented in a collegial format.

All of the content is accurate and explained in a manner that is easy to grasp. There are some minor typos in some of the activities, but they do not confuse the reader. The text is bias-free and includes interesting examples that students can relate to.

The overall content is highly relevant and will age very well. Updates would definite be easy to handle and manipulate. By breaking down each chapter into a variety of content areas, readers will be able to focus and review areas of concern.

Having read several print and online texts of a similar nature, it was a pleasure to come across a text that is clean, consistent, and concise. Each topic has an appropriate amount of information to get the point across as well as tips that lead the reader to additional information. The presentation is consistent throughout without any bloating often found in print texts.

The authors of the text did an excellent job of producing an online text that is consistent and easy to use. No tricks that make it difficult to navigate or confusing to read.

One aspect of the text that I especially like is the modularity that allows for the use of a particular chapter or page(s). Too often texts have chapters that make readers feel like there is no end in sight. The concise nature of this work blends extremely well with the modularity of the complete text.

What makes this text easy to adapt is the layout from beginning to end. Each chapter and section scaffolds upon the other which will allow students to build their skills in a natural manner. Knowledge attained will easily transfer from one topic to another as they move through the book.

While I believe that the text is excellent and I have adopted it for my class, I do find myself frustrated by not being able to move from one section to another within a chapter without having to go back to the contents list. This surprised me because most books and tutorials have forward and backward links, especially within chapters.

There are a few grammatical (spelling) errors in several of the exercises, however, they do not interfere or confuse the reader.

This is definitely a professional work that has no cultural issues and is an excellent example of a non-biased text.

While looking for an OER text I was delighted to come across this book. The content and flow fit in with my class content extremely well and is an excellent resources for courses in the liberal arts, general research, and library-centric classes.

This book is accurate and comprehensive. I would not hesitate to use this resource with undergraduate or graduate students as a beginning primer for research.

The book is relevant and timely in regards to the various resources and tech tools it mentions (Google Scholar, EndNote, Ref Works). Given the subject matter I suspect that this book will have longevity to users.

The text is clear and provides definitions for jargon/technical terminology that is used. It is very comprehensive which might be a bit intimidating for the first time reader, but all elements needed for cogent research are included and therefore necessary. I appreciate the use of student scenarios as a way to step-by-step show the thinking process of choosing research questions.

Very consistent and thorough.

This text would be ideal for use as single chapters in courses where the content is needed. While the content is crafted with Ohio State University students in mind it is still very relevant for use by students and scholars. I am already thinking how I might use this next semester with an undergraduate honor's thesis student - both as modules to be read but also as a reference source.

The book is organized in a logical manner but spends only a brief amount of time about qualitative and quantitative research as peer-reviewed sources and only gives basic definitions for those two terms. I would perhaps suggest an additional section on qual/quant/mixed methods research methodology and perhaps a quick overview of research methods or samples via discipline. Additionally, a mention of the common IRB process for Human Subject Research might be helpful to those students using academic sources that discuss that process. It is a very clear text and this could be added with just a few pages of information that might be beneficial to students.

The text does not include an index or glossary. However, it covers a complex (and dry) subject in an economical and stimulating fashion. Each reader would learn about the subject from the basic text but the authors have enriched the text by embedding audio-visual resources, download-and-keep checklists and formative activities of excellent quality.Chapter 9 'Making an Argument' is particularly strong and complements Chapter 1's analysis of research questions well. It is an excellent resource for undergraduates, post-graduates and beyond, and could also be useful for professionals researching topics to support evidence-based practice protocols.

More tips about applying facets to search results on services like Summon, EDS or Primo would be a useful addiition. I was surprised the authors did not employ language to frame the skill development in the language of 'employability' and life-skills, which might hook readers who are not planning to engage in academic research in the long-term.

The accuracy of the book was excellent, My score would have been 5, except the advice about copyright legislation and fair use is only applicable to students of Ohio State or elsewhere in the USA; so an institution in the Britain, Ireland or Europe would not be able to use or recommend chapters 11 or 12. However, these chapters are well-judged for the intended audience; succinct and comprehensible, where so many guides are too woolly or arcane to be useful to a general readership.

Chapter 1 had a dead link to an audio-visual resource. The explanation of how to use Wikipedia for academic study was nuanced, classic and practical. The explanation of how to use truncation and wildcards were similarly time- (and platform-) proof. There is much current interest in 'fake news' and the manipulation of Facebook and Google algorithms. So it could be timely to add a section on the known issues and some practical strategies to compensate for them.

The authors use excellent, clear English that should be comprehensible to anyone with academic english reading proficiency. My only qualms related to an ambiguous use of the term "poster" (this word has a particular meaning in an academic setting which was not explained) and more extensively around the slightly simplistic and dated language used for the university library catalogue and abstract & indexing databases. One of the activity sheets is structured like a decision-tree and starts with the question "are you working from a database"; with modern resource discovery platforms and other aggregating tools, students may not be able to tell whether they are looking at results from a single database, all the databases from one supplier or multiple databases from a variety of suppliers.

The stylesheet and planning of content is elegant and the quality is consistent throughout the text.

Each chapter is split into useful subsections, with clear formatting to demarcate between topics, tips and activities. The authors have also helpfully embedded hyperlinks to relevant chapters or sections earlier or later in the book.The length of individual subsections is consistent to make reading online easy (balancing scrolling and page turning). However, the length of embedded audio-visual materials varies so a student planning their time might be surprised in places.

The text has a sensible progression of topics, with hyperlinks back and forwards to connect relevant topics. And the final chapter, 'Roles of Research Sources', pulls together the lessons learnt with a useful acronym (BEAM), giving the book a strong ending.

I accessed the text on a variety of browsers, screen sizes and operating systems without any problems with the interface.

I only spotted two minor errors - site instead of cite and White's definition (page 186) without an apostrophe.

Considering the book is not overly large, the guide manages to be very through and comprehensive guide to locating sources and using them correctly. It even goes further in giving some great information on making an argument and writing out the research. The chapters are in easily digestible chunks covering the process of searching and evaluating resources in a useful and cross-discipline manner. It covers the source search process of research in an easily digestible manner.

The topics are accurate and have been written in a way that they will not date too much. The links and examples of the services provided may need updating to keep them accurate but the nature of the online format makes this easily possible. The Copyright chapter is obviously only applicable to those studying in the US. Having a version of this chapter available discussing copyright law in the UK could be useful any access the course for a different location.

The topics, examples and videos used are relevant and useful and should not date too much. The links and examples of the services provided may need updating to keep them accurate but the nature of the online format makes this easily possible. Some of the examples and links are specific to Ohio State and America and this can limit the relevance for students who do not have the ability to access Ohio State resources or are not based in America. Also the copyright section specfically is obviously only US copyright law limiting it's usefulness for students based in other locations.

The writing style is straightforward and easy to follow. It is sometimes slightly repetitive but overall the information is clearly presented and the vocabulary used is not too advanced. The style is informal and it makes a weighty topic much easier to process. I think it would be useful to have a glossary in the resource for students who maybe have not come across some of the topic specific words before and need them defining.

I was impressed with the consistency considering the work is made up of different author’s contributions. I could not identify different voices within the text, which helped improve the flow of the work. The arrangement of the contents tab is very useful to help navigate to specific sections of chapters as well as the overall chapter.

The layout of the book makes this modular. You can choose which sections to look at in any order and they read clearly and separately well. The other sections are signposted throughout the text and you can link back through to these using the hyperlinks provided. I think the order could be slightly improved by moving the citing and copyright information after the information on argument and writing but because you can choose how to read the book then it is not really an issue. I think it is important to note that if you cannot play the video content or the links in the book are Ohio State Specific the book does lose some of its positive features.

Overall, the structure is straightforward and logical. It flows in a manner that is easy to read and to process. Using the navigation you can work your way through the book in any order you feel is appropriate. As I stated I feel the referencing and copyright information could be in a different place but because you can choose to read this in a different order, it does not really matter.

Having read the online version on both a PC and a tablet I found the interface both easy to use and accessible. The page and chapter length worked well on both platforms and it was easy to access the links and activities contained within the resource. I could not access the videos on the PC due to not having Adobe Flash and it would be useful to have known I would require this to access the resource in its entirety. The video content is a refreshing change to just text and the images used are overall relevant. The videos do not all include a text version and this would be useful for accessibility. A few of them do have this option. Some of the images in the text viewed blurry on my PC and tablet. I am not sure if this was an issue with my own software or an error in the book.

I did not notice any errors during this read through. In some places, the text was a bit repetitive but this not disrupt the flow too drastically.

The examples used are not offensive and are diverse in their range. They have not given examples that define the guide for specific subset of students, which makes it more applicable.

Just for accessibility purposes, I think all the videos need a text version not just some. In addition, the RefWorks program has now been updated and it is called New Refworks with a changed logo and this could be updated in the book along with the guide to setting up Refworks if your institution subscribes. I feel that there are many links that you could not access unless you were an Ohio State user and this could disrupt the flow of the book for some users.

The book provides a comprehensive introduction to the use of sources in academic writing.

The book is a polished, professional and appropriate tool to help students improve their information literacy.

The content is relevant for undergraduate students and their instructors. It focuses primarily on fundamental approaches to finding, evaluating, and deploying sources in order to enter the scholarly conversation. While the authors occasionally mention a specific tool, or insert links to outside sources, these are placed within "Tip" boxes that can easily be updated.

Because this book was created for students at Ohio State University, it is sometimes quite specific about tools or processes that are unique to OSU. Instructors using this book at other institutions may sometimes need to suggest their own's institution's available tools to keep the text relevant for their students.

The book is well-crafted for an undergraduate audience, taking an easy-going, friendly tone and clearly defining key terms and concepts. It is also accessibly structured, making it fairly easy for users to jump between topics, rather than requiring a linear read. Links between related sections are provided wherever it is appropriate.

The book uses a consistent design scheme and structure. Features that appear in each chapter include graphics, tip boxes, examples, activities, and summaries.

Each unit of the text stands on its own and could be easily assigned as an individual reading. Rather than being self-referential, the text will suggest that more information on a related topic can be found in one of the other modules.

The text is organized to flow in roughly the same sequence as a typical research project. Students who are reading the text while working on a project should find individual sections logically presented and relevant. This is clearly not a text designed as background reading; rather it functions best as "just in time" information for students working through the research process.

I found the text quite easy to use in it its online form. It is visually appealing, easy to navigate, and thoughtfully arranged.

I noticed a couple of typos, but no significant grammatical errors.

The examples provided are of broad interest, and most readers will have some familiarity with them. There were no insensitive or offensive comments or examples.

Choosing & Using Sources: A Guide to Academic Research is a practical tool for novice researchers. It asks students to begin the process with a research question, and then provides a step-by-step approach to creating the question. All the other chapters flow from this effective beginning, and should increase students' information literacy by helping them understand types of sources available to researchers, the relationship between sources and information needs, how sources should be evaluated, and how they can be deployed effectively and ethically. Additional chapters on argumentation and copyright round out the book's overall usefulness to students engaged in a research project. This book could be easily paired with a staged research project, and would provide students with the "just-in-time" information they need to successfully complete the assignment.

The aspects of academic research that are prudent to cover within the first year of any undergraduate student's general education are all covered within this textbook. From an introduction to the ethics of source use to crafting basic Boolean search strings, all facets of entering scholarly discourse are addressed in brief chapters that feel modern and accessible. While instructors may wish to supplement or replace some of the exercise sets in the text with their own assessments, the content of the text provides ample coverage if selected to serve as a primary textbook for a foundational information literacy course.

The book is accurate in addressing the current state of the information landscape as encountered in the realm of academic research, as well as the legalities of copyright and fair use.

All content within this book is current and the content within chapters sections are written in a style that today's undergraduate students will be able to learn easily from. Many of the concepts, processes, and principles that are covered in the text have an inherent longevity that will prolong the relevance of this text past its initial publication date. However some chapter sections, tutorials, and videos are institution-specific reducing the overall relevancy of using the entire text at other locations.

The text is written in a clear and concise style that current students will find very accessible. The authors consciously defined any technical terminology or jargon as it was introduced throughout the chapters. Furthermore, the technical concepts that were more complex to define are often accompanied by visuals to help convey what is being defined.

The terminology and format of the book, along with the linked exercise sets and visualizations, provide a solid consistency that will helps students focus on learning the content rather than being bogged down with understanding the textbook format.

Instructors could easily parse different chapters of this book to use for modular instruction, especially in "one-shot" or other limited instructional scenarios. Some of the chapters are a bit self-referential which may generate a minor degree of confusion if used out of the holistic context.

Organization/Structure/Flow rating: 3

While there is a logical flow to most of the chapters, some seem a little out of place such as the "Making an Argument" chapter. I would have preferred a division of chapters into sections, where the writing-related chapters were separated from the source-related chapters. I also think the chapters that covered Copyright, Fair Use, ethical source use, and citations would have a stronger flow if organized together in their own section.

The ability to navigate through the book from the table of contents page is a great feature for students, especially when the instructor is choosing to assign only particular chapters or work through some of the chapters in a different sequence. The linked exercise sets are also easy to navigate through, allowing students to focusing on applying learned concepts rather than learning new interfaces. However, throughout my review some of the linked external content would not open for me and links to external materials always have the possibility of changing which may result in future inaccessibility

No grammatical errors were detected when reviewing this book.

This book is not offensive nor culturally insensitive in any manner.

For any instructor looking for an open textbook to orient undergraduate students to the basics of the academic research and writing processes while simultaneously providing context of contemporary issues surrounding these scholarly activities, this is a comprehensive and accessible choice!

This text offers a comprehensive breakdown of the academic research process, with special effort made to demystify jargon that may present itself in either the classroom or library environment. Beginning with establishing a research question and carrying through to integrating and citing sources, the text includes practical tools for students to use in their own research, as well as links to supplemental information. If anything, the text errs on the side of providing too much information, such that a novice researcher may feel overloaded.

The text offers an accurate articulation of the research process, and avoids bias by covering a wide variety of potential information sources, including the use of web search engines other than Google.

Because the information landscape is constantly shifting, the text will require fairly frequent review. This is particularly important when it comes to how web sources are addressed. For example, the book does not address fake news and/or dealing with problematic web resources, and it glosses over use of social media as an information source. However, the concepts related to the research process itself change very little, and the information presented about them has staying power.

The text is written in accessible language, and works to address uses of jargon that are typical within the academic environment by providing explanations for what professors typically want when they request a particular item in the research process. This is an effective way to establish relevance with students, as well as clarify academic expectations.

The language within the text is consistent and accessible, with helpful insertions of definitions and/or links to explanatory supplementary information online.

The text's sections are clearly and logically labeled, and could very easily be plugged into a course in part or whole.

The order of topics in the text follow the research assignment process, from point of assignment decoding through to writing and source citation. Given the audience for the text and its intended purpose, this makes great sense.

The text contains links to many outside web sources that may provide helpful supplemental information for the reader; however many of these links were found to be dead. Comprehensive review of all links is highly recommended. In addition, I recommend continuing review of available videos related to the topics, as many selected are either rudimentary or contain dated material.

The writing and grammatical quality of this text are of the highest quality.

The text is culturally relevant and inclusive in its examples.

As stated, this book holds great utility and relevance, but requires updating for links to external web resources. It will also need to be adapted to keep up with the changing landscape of information sources themselves.

Reviewed by Craig Larson, Librarian, North Hennepin Community College on 2/1/18

The book is very comprehensive, sometimes almost too much so (sections on copyright seem to be more detailed than the average college student would need or perhaps be interested in; the section on the lifecycle of information, while interesting, also is a bit questionable as to its overall relevance). Instructors who choose this book for a one- or two-credit information literacy course will have much more material at their hands than they can reasonably cover in a semester. This book would make a good companion volume to just about any course involving research.

The content is accurate and unbiased. As an example, I was interested to find that the author actually recommends that students use Wikipedia, at least in the very early stages of research, to get an overall picture of their topic. So many college instructors, regardless of the subject, seem to have a strong aversion to Wikipedia. Here, the author actually goes into some detail on how using the references in an entry can lead the researcher to additional sources he/she might not find through other means. Some of the activities are a bit misleading or written in such a way that there could be more than one right answer, which isn't necessarily an error, but could be tightened up a bit.

The content is largely relevant and up-to-date, though I was a bit surprised to not find a section addressing "fake news," which has become such a watchword over the past year. I was also a bit surprised that, although the author has a section talking about which "neighborhood" certain types of information "hangs out," there wasn't a discussion of different domain names, such as ".edu," ".org," and ".com" and what they indicate to readers. Also hampering the book's relevance somewhat is an overabundance of examples and activities that require an Ohio State student ID to log-in. Many of these would have to be re-worked or re-written for the book to be useful at other schools.

In large part, the book is clearly written and new ideas are clearly explained. The writer does a pretty good job of avoiding jargon and technical terminology or where it can't be avoided, of providing examples and clear definitions of terms. Some of the activities aren't so clearly written that there is one obviously correct answer. Also, some of the scoring of activities isn't clear enough to indicate to the user what was wrong and why it was wrong or even the correct answer that should have been chosen. Not every concept is adequately explained or thoroughly developed (for instance, the crucial process of moving from an initial reading to a research question could use further clarification and development). Another area that could use further discussion and development would be how to use databases.

The book is largely consistent, though there are occasions where the consistency falls through. For example, most of the accompanying activities will open in a new window, but not all. There were several occasions where this reader closed out an activity window and closed out the entire book as well. This is an area that someone really should take a look at, as it can be confusing and irritating for the user. Also, the fact that many of the book's activities require an Ohio State student ID effectively locks out users from other institutions.

The book is largely modular, with sections that can easily be broken apart and assigned at different points in the course. There is a very useful table of contents, broken down by subject into smaller pieces that can easily be accessed. As mentioned previously, the book is very comprehensive, almost too much so at times, so having this table of contents is very helpful.

The book is fairly-well organized, though there are things placed in odd locations that could be touched on earlier or later, as the case may be. For instance, there is a good discussion fairly late in the book about deciding whether to quote, paraphrase, or summarize, which would have been much more useful if it was placed in the section of the book that directly addresses each of those activities. Instead, it is placed in a section on academic integrity (which, again, is very Ohio State-specific, too much so, really). I also question the relevance of a chapter on creating an academic argument, which if it is to be included at all, would seem to make much more sense earlier in the book, when students are learning the basics of research and how to apply it to their writing.

The book is largely free of significant issues, although as mentioned previously, many of the activities require an Ohio State student ID to log-in and use, which makes them useless to students from other institutions. Also, the activities are sometimes difficult to follow--one doesn't know why one answered incorrectly or what the correct answer even is in some instances. And the fact that some activities open a new browser window and some don't can also be confusing. There are a few activities that lead to broken links.

There are the occasional run-on sentences and spelling mistakes in the text. It's almost impossible not to have some issues in this area. However, the infrequent errors don't detract from the book or its overall usefulness, though it might be a good idea for someone to go through the text and try to clear some of these up.

The book does a good job of avoiding being culturally insensitive or offensive. Activities and examples are written in such a way as to be inclusive. Many of the examples link directly to sites that deal with minority themes and issue.

I think, on the whole, this is a very useful book and one that could be put to immediate use in many instances. However, the number of activities and examples that require an Ohio State student ID to access make this less relevant than it could be if the author had striven for more universal examples.

Reviewed by Mairéad Hogan, Lecturer, National University of Ireland, Galway on 2/1/18

This book covers the subject matter in a comprehensive and detailed way. The way in which the material is presented is very suitable for students who have not previously been involved in academic research as it starts at the very beginning and assumes no prior knowledge. It has additional features that help to reinforce the material, such as activities and MCQs. These help to reinforce the learning and test the reader’s understanding. Additionally, the examples used are very useful and helpful in gaining understanding of the subject matter.

It goes into the material in depth and not only tells students how to progress their research but also explains clearly why they should be doing it this way. For example, it explains to students how to differentiate between good and bad sources. However, I have one small concern with this aspect. They do not tell students how to differentiate between different standards of peer-reviewed journals. They do mention looking at citation count but state that is not a useful measure for very recent articles. Some discussion on determining the quality of the journal itself would be helpful. For example, looking at citation counts for the journal, rather than the article would be one example, as would looking at rankings.

Overall, I would see this as an excellent reference book to last students through their academic careers.

The material itself is accurate. However, many of the links to additional material either do not work or are inaccessible to those without OSU credentials.

The material is mainly presented in a way that will last. However, many of the links no longer work so these should be checked and alternatives put in on a regular basis. Additionally, there are links to videos that may not be there in the future, although all I clicked on were available. However, the text description of the videos did not work. Many of the activities (MCQ’s etc) have a dated feel about them in terms of layout and interaction. The design of them could do with some updating.

The writing itself is very clear and easy to understand. Diagrams are used to good effect to clarify concepts (e.g. use of Venn diagrams to explain Boolean concepts). However, some of the terminology is not as clearly defined as it could be. While terms are generally explained clearly in the text, it would be nice to have a glossary of terms. Additionally, the MCQs are not always clear as if the reader gets an answer wrong it is not always apparent which is the correct one.

The book is consistent in writing style and interface.

The book is structured in a modular format whereby the reader can dip in and out of different sections, as they need to. Equally, for a student starting out, it is structured in a way that is likely to follow the steps in the same order as the student, making it a good companion to their research projects.

The book was organised in a very natural and sensible way and flowed smoothly from one topic to another. Links were provided to related sections of the book where relevant so that if the reader forgot what was meant by a particular topic, they could easily hop back and forth. The book started at the very beginning with good coverage of developing a research question and then progressed through tools and sources to help with this. The additional activities were all web based, which works fine if you have easy access. However, I was using a kindle with poor broadband so struggled to access it at times. It also felt a bit disruptive leaving the book to do the activities. It’s also not always clear whether links lead to another part of the book or to an external site. The tips are a useful addition. The stand out when flicking through the book and help to reinforce the important points. It is also useful the ways steps are clearly broken down into sub-steps.

I downloaded it to Kindle, and found a number of issues. It struggled to deal with larger fonts, resulting in some text not being visible.. There were also references to “the bottom of the page” but the bottom of the page varies depending on font size. Not all of the activities worked. Some of the activities required OSU credentials to access them, which was frustrating.

There were some minor grammatical and typographical errors but nothing major.

The book is very US centric in its use of examples. For example, there is an American football example and news sources referred to are US based generally. Additionally, copyright discussion is US centric.

Overall, I found this to be an excellent book that will help students in their research projects. I think it is a book that they will use for a number of years as it is has sufficient depth to help at different levels. The one main change I would make would be to broaden OSU references and activities so they are referring to databases in general, for example, rather than simply talking about the OSU one. Much of the material is relevant regardless of institution but a reader unfamiliar with databases would not be aware of this and might skip over some very useful information.

Choosing and Using Sources is an extremely thorough text taking readers through the research process from formulating research questions to fair use and copy right issues. I particularly liked the online examples and resources including quizzes and videos. The table of contents is thorough but there is not a glossary. While this is a strong text some discussion of theory and how theoretical frameworks are used in academic writing.

While the text could have addressed additional areas, the authors were accurate and detailed. Chapter 8 - How to Cite Sources is well done and accurately takes novel researchers through when they should and should not provide citations.

The authors present how to develop, approach, and conduct sound research in a well thought out format. This text is up-to-date addressing issues like Wikipedia and Google Scholar. While issues around these information sources will change, the way this text is set up, it can easily be updated in the future.

The book is well written, clear, and easy to follow. Jargon such as primary, secondary, and tertiary sources were explained clearly with appropriate examples. This text will be accessible for my students and most others pursuing advanced degrees.

The authors are consistent throughout the text when discussing topics like presenting arguments and the relationship this has with concepts like research questions and the sources researcher select. While consistency is expected is difficult to do especially when writing as a team. More impressively is the consistency of supplemental materials throughout the text.

The book has long chapters and occasionally I had some difficulty knowing where one section ended and another began but overall it is readily divisible. Another important aspect of the text are the supplemental materials like online quizzes and videos which are also clearly align with the sections in the text.

I was skeptical at first when I began reading but the overall organization of this text is good. Even though the text is about writing and sources, a section of theory and incorporating theoretical frameworks would have strengthen the book. However the topics selected flowed well and led potential researchers through a logical process.

A few problems linking to sum supplemental materials but overall I was impressed by the quality of the graphics as well as the links to quizzes and videos that were provided.

I did not come across any grammatical or typographical issues.

I did not see any cultural insensitive examples or information provided. However I also did not see a lot of racial or ethnic diversity in examples throughout this text. Overall, I feel the authors approached the subject matter appropriately.

The text is quite comprehensive regarding finding, using, and understanding sources. It provides the process of sourcing from start to finish with examples and activities provided throughout to support the reader. Various ways to find sources are described. There is a focus throughout on software and databases for the students at the authors institution and that can be confusing to readers from other institutions. The information provided regarding citing, ethics and copyright, and fair use was informative and would be beneficial to the reader. There were sections throughout that could have been more in depth and more specific. For instance, when going over the various ways to cite sources, additional examples could be provided and the version/edition should be listed. For instance, was the APA citation in APA 6th edition format? Also, make sure to address citing from secondary sources as students do this often and tend to cite what they read even if they read it from another text. The TOC was helpful and allowed ease of understanding what was to be covered in each section. One main complain that I have was regarding the additional information provided to help the reader in writing a paper. This information would be helpful for basic college writing but not for academic writing, thesis or dissertation writing. The sections required for some of these papers are not discussed and the text eludes that the sections provided regarding writing an argumentative piece would be appropriate for all. Also, synthesizing information could be explained a bit more and with more depth. Synthesizing includes more than critiquing and summarizing. All in all, the sourcing information is spectacular and the additional information could be expanded upon.

Accuracy of sourcing was spot on. Some of the additional categories discussed, as mentioned in the first section of this review, could be expanded upon to fully explain that category, if it is to be included in the book. The examples and activities provided were quite good and would be very beneficial for students to apply what they are learning in real-life contexts. Links were provided for extending information. I did not attempt to open every link but making sure they are up-to-date will be important as time goes forward. I also feel that the section on popular texts can be misleading. Stating that the Washington Post is "popular" eludes that it is not reliable or valid. This is not necessarily true as many experts in various fields write sections in "popular" newspapers.

As previously stated, a lot of links go to OSU resources. This could be problematic for any reader that is not at OSU. More information should be provided to support any student in the world as that part would be confusing to many students.

The text is easy to read and follow. All new information is explained and then examples and activities are provided. This is student friendly and allows any reader to quickly follow along and understand what is being stated, especially regarding the sourcing elements. As stated above, there are some sections that could/should be expanded upon for clarity and this might be best for beginning university students but the text was easy to understand in regards to sourcing, citing, and fair use. More information on how to use the sources and sections of papers would be beneficial to all students.

Each chapter seemed to follow a similar structure that followed the TOC.

Modularity rating: 3

Reading the book online provides ability to chunk the text based on assignments and can be read chapter by chapter, entirety or starting at different places. Due to the extensive amount of outside links and examples, this would be quite different if read in paper format. This book truly has to be read online to ensure benefit from all of the additional activities, links, examples, sources, etc. In addition, the many links specific to OSU would not be helpful for other students.

The organization is consistent from chapter to chapter. Information is explained and then examples and activities are provided to further knowledge. This works well for readers that needs examples.

Using a laptop provided no issues. However, when using a smartphone, the pages changed in size and various display features did not load properly or at all.

Very few grammatical errors were noticed.

No cultural issues noticed other than the many OSU references and sources. This could be offensive to other institutions as they will not be able to access many of the links.

The book is error-free and appears to be free of bias.

The book is pitched to an Ohio State University audience, so some of the resources pointed to would not be the same as a potential adopter's institution might select. In addition, the book needs some updating regarding the impact of social media on the information cycle. Social media formats are mentioned, but a fuller treatment of how they fit into the information climate would be a good addition.

The text was clear and easy to read, and provided numerous examples for its points. It also did not rely on jargon in its explanations, which makes it much more accessible.

The text was consistent in its use of terms. I found its tone consistent, as well as the level of explanation for the wide variety of concepts explored.

The organization of the text into units makes it very easy to break the content apart into smaller units and use it for a variety of purposes. I could see using the content for different parts of several courses, as well as incorporating it into e-learning content.

The topics are presented in a logical fashion, following the path that a typical research assignment might take. This will also make it easier to fit within the flow of a course that uses the textbook to teach about the process of academic research.

The interface of the text itself works appropriately, but some of the ancillary quizzes and extra material did not work so well. Many of the graphics did not work as well within the pdf format as they do in the web format.

The textbook was free of grammatical errors and was easy to read.

The book didn't seem to dismiss any possible research method. Instead it provided suggestions of how and when any individual research method may be relevant.

The book was published last academic year and the content included is still relevant, mostly because best-practices in research (and research writing) haven't changed much.

The volume of research methods students can use given the internet's power is ever increasing, yet the book does well to isolate a handful of long standing tenets that academic writers have used for decades while allowing for discussion of web-based writing and multi-modal presentation methods instructors may increasingly require students to use.

Each section is concise, clear, and easy to follow . . . for me.

I assume students will be capable of reading the text, performing quizzes provided, and plotting out a research path to complete their assignment(s).

Then again, as an academic I obsess over these issues. I can see a student yawning while reading this text.

The content isn't especially fun to read yet the information provided in relevant and time-saving if students are willing to relax, read actively, and apply the material to the assignment their instructor has given.

I don't imagine many students would seek the book out and read about research methods, yet an instructor can pair excerpts from the book with specific assignments along a student's research path to help the student retain and apply the helpful suggestions in the book.

The text does well to allow students to name the process they're going through when composing a research question then deciding on what research path fits their question. Students are guided to consider what blend of qualitative / quantitative, primary / secondary / tertiary, or public / professional / scholarly research will fit their research and writing goals.

The book refers back to the same terms throughout and provides students with active learning worksheets to plot a research AND writing plan to complete their work, one they could conceivably follow throughout their academic and professional career.

Each subheading contains, on average, not more than a page of content allowing instructors the ability to easily limit reading assignments from the book to concise, focused sections.

The book is very process-based, and follows the workflow necessary to write a successful academic researched assignment.

The limit of this strategy might be students being overwhelmed with so much discussion of process they'd be paralyzed to inaction.

An instructor, then, would have to be direct in assigning reading materials relevant to a student's immediate research goal.

I like how the text follows the path a student would follow: from narrowing a research question, selecting and reviewing research materials, then choosing how to implement them ethically in writing.

It also details how to process research considerations students may not consider including how to archive research results, to respect copyright law when publishing blog posts or submitting student work to an online repository.

The text contains many online activities, sample research artifacts, and instructional handouts. Some require on Ohio State student authentication. The text is still useful without access to these materials, though an instructor would have to alert students to this issue.

The content appears to be accurate to 2016, with some acknowledgement that finding sources is an activity that has seen many changes in the past few decades, and will likely seem more, and rapidly.

Information discovery and retrieval is a rapidly changing process in a changing field. But much of the content in this textbook—as far as general advice and instruction for finding resources and the ways to use them—remains relevant. As information processes change and as information uses change, I have no doubt that librarians will be at the forefront of maintaining the relevance of a textbook like this one through various edition changes.

This textbook is clear, and accessible to researchers at all levels. Jargon, where present, is well-explained, and the contexts for the various components of the textbook are provided.

The text and frameworks in this book are consistent with ACRL frameworks as well as with the ways librarians tend to talk about finding and using sources. Furthermore, the book consistently uses the same terminologies to clearly explain sometimes difficult practices.

I would be very comfortable using any chapter of this book to teach a component of the academic research process. The chapters are discrete, with well-defined boundaries. The modularity of this textbook helps reinforce the overarching idea in this book: the iterative research process. Students might read the chapters in virtually any order, and come away with a valuable understanding of the research process.

This textbook presents the research process in the way that many students and faculty think about the process—from the perspective of the end goal, and through the organizational structure of an academic paper. But, it also indicates throughout the process places when the researcher needs to revisit an earlier step, to modify the project, or to make the end product more meaningful.

No issues in the interface; nothing distracting from the content.

Some minor punctuation errors, but no grammatical errors that distract from the content.

This textbook comes from an American perspective for ways of searching for, retrieving, and using information, as well as the traditionally American ways of constructing arguments. Though there is not discussion of other cultural ways of arguing academically, this textbook does not dismiss or otherwise denigrate other cultures; nor is it insensitive in any way.

Many examples are university-specific to the libraries at Ohio State University, as should be expected from a textbook such as this. As such, this book will be most helpful to students using the book at OSU. However, instructors using this book need to be aware of this focus, and must prepare to supplement with materials accessible by researchers outside OSU.

This textbook is comprehensive. It goes in-depth covering the topics of research questions (specifically how to narrow down topics), types of sources, sources and information needs, precision searching, search tools, evaluating sources, ethical use of sources, how to cite sources, making an argument, writing tips, copyright basics, fair use, and roles of resource sources. The textbook hits all of the topics that I plan to cover in my upcoming classroom-based research course with the exception of techniques for completing and writing a literature review. The textbook touches on the topic through a section on "background reading", but does not go in-depth. Otherwise, the textbook covers every aspect of academic research.

I found no errors or bias issues in my initial first read of the textbook.

The information and techniques provided within this textbook are up-to-date and relevant for academic research. I reviewed several textbooks before choosing this one for my upcoming masters-level classroom-based research course. I chose this book because of its relevance in regard to the practical skills needed in order to complete research assignments within the course, as well as, writing a capstone research paper.

This textbook is clear and exceptionally readable. It is organized by research skills in an order that makes sense to the reader. For example, the book begins with a chapter on choosing one's research question. Verbiage is clear and concise for all levels of academia to be able to effectively utilize this text.

This textbook is consistent in terms of terminology and framework. Each chapter of the textbook builds on the last. The reader is not necessarily expected to have prior knowledge of research before reading chapter one, but should easily be able to have a good frame of reference for academic research by the end of the textbook due to its high-quality framework for scaffolding knowledge with each chapter.

This textbook does a great job of sectioning academic research into small bites for the reader. It was easy for me to create modules from the textbook's chapters, spreading the information within the text over an 8-week course. The modularity of this textbook was a selling point for utilizing the textbook with students.

This is a well-organized textbook. Each chapter builds on prior chapters. Chapters are organized in a logical manner. The first chapter begins with the purpose of research questions and builds content to assist the reader in narrowing down options for research questions. The textbook progresses to assist the reader in building skills as an academic researcher throughout the textbook.

No interface issues were discovered during my initial exposure to the online format. I printed the PDF (because I still love paper) and all display features printed properly. The online navigation is easy to use and pleasing to the eye, as well.

No grammar issues were detected during my initial review of the textbook.

This text is not culturally insensitive or offensive in my opinion.

The text did a great job of covering the subject and the table of contents were laid out well. The content was well thought out.

I found the accuracy to be good. The content is a good representation of what a student needs to know in order better understanding library research.

The content itself is good & should stand the test of time for the near future. The only exception is that even though it's only one year from the publishing date (2016) many of the links are broken. And I would have preferred a OER text that was geared more generally for application to any institution vs. the inclusion of OSU specific references, links, resources.

For a text written to a 4-year university/college audience the text was good. For a 2-year community college audience some of the terminology would need to be defined.

I found the consistency to be good. It followed through each section with including tips, activities, etc.

I think the modularity was good. And the text could easily be broken down into smaller sections to be used as units by themselves or refresher units. The only issue would be where there are links within a module that link to other modules. Add to this that these links didn't work-- I rec'd errors each time I tried a module link.

The overall organization and flow as great. As stated on p 6 ("... as though you are conducting a research project while reading them [the sections]...") this made my logical side happy.

I like the links to activities for students to practice the skills being taught. The problem though was that many of the links no longer work. Additionally, many of the links are to areas not available to users who are not affiliated with OSU. And as mentioned in another review section, module links to other modules didn't work either.

I found the grammar to be quite good with only a few exceptions or where it was clunky at times.

I thought the text was neutral in this area. Nothing that blatantly jumped out at me.

I appreciated the link to application of research to other areas of our lives outside of academic research. I try to get this point across to students, especially when they are hesitant and resistant to library research. I found the "tips" & "summaries" to be a nice added 'pop' & easy for referring back to later. I liked the bold letters/words for emphasis. And the suggestion to "brush up" on p 31 was a nice touch vs outwardly assuming they don't know. The downloadable templates are a great resource for students. Overall, I found the text to be a good resource.

This text is extensive! Like the title suggests, it truly is a full guide to academic research, from developing a topic, finding sources, and using them appropriately. It also follows the logical order of the search process, from identifying an information need, evaluating source quality (and purpose), and how to perform complex searches. It also highlights several common areas where academic research can be performed, from the college library catalog to specialized databases and how to find academic sources on the free web.

The book also covers what to do once sources have been found, including the importance of properly citing sources, ethical use of source material, and how to cite unusual or non-standard source material. It then moves into addressing the writing process: developing an argument and idea, writing tips, and a large section on copyright, fair use, creative commons, and public domain.

The table of contents is very granular, which is helpful. The sections vary in length, but given the overall size of the book (190 pages) having a very specific TOC is useful when returning to the text as a reference source.

I did not find any objectionable or questionable content. The authors have done a good job of selecting examples for each section (often with associated online activities or examples linked out to the web) that are varied and unbiased, but also represent realistic examples of what students might be encountering during their research process. I was really pleased when looking through the section on citing sources - styles can change, but the book is written in such a way as to be comprehensive about the purpose of citing sources, and links out to many helpful web sources, citation tools, etc so the information will remain accurate in the textbook even if the style guides themselves are updated in the future.

The section on copyright is similarly done.

See previous note - it is clear the authors have taken care to include examples that will remain relevant, not evaporate into popular culture, and provide flexibility where the content may be updated or changes (such as copyright law and citation style guides). They do provide a LOT of external links and activities, not all produced by Ohio State. So it's possible that some of their links may break in the future. It does appear that they have made an effort to either link to open sources they control, or which are unlike to change significantly (ie: government websites).

If I were using this text, I would probably modify some of the resource sections (eg: databases) to reflect those that the students at my institution have access to, though the writers do make a point of identifying OSU access-only resources where applicable. I would also update the copyright/plagiarism section to include our college's student handbook blurbs, etc.

The tone is extremely approachable in all of the areas I checked. This is extremely important in academic research where there are a lot of areas of possible legal entanglement, and the authors have done a credible job of breaking down complex concepts into approachable prose and examples.

The textbook is consistent in both writing and structure; however, I do with the table of contents was split into sections in the same way the content is. Page numbers are given though, so that's not really a big deal. There were one or two places where I saw formatting errors, but nothing overly distracting - it did not adversely effect the content.

It is visually appealing and for the most part, easy to navigate. No huge blocks of text, and it also intersperses activities, tips, and examples. The text is also organized in such a way that it can be used as a reference, without needing to be read from start to finish in order to make sense, which is helpful for the researcher who may need to pop in for just pieces of the work.

However, there is a strong presence of external sources (often OSU library webpages) and activities that are linked out of the text. The writing itself is certainly standalone, but the book would lose a lot of its character if it were printed and not viewed digitally. I would have liked a References or bibliographic section that listed some of these resources, but there wasn't one, meaning the user would not be able to search for the resource if the linked text didn't work.

I can see the potential for too many asides for activities to be distracting, but they are generally held to the end of their relevant sections, so it wasn't too overwhelming. The organization follows a logical research process, walking the reader through from beginning to end.

As mentioned before, there are a few places where it looks like images have distorted the intended formatting, pushing items to empty pages, etc. But these instances are rare. A few of the images could be higher resolution, but they were certainly legible (and I was viewing this text at 125% zoom on a larger screen, so my experience is probably not representative of every reader).

It is long though, and I would have loved to be able to jump to sections through anchor bookmarks in the content page - that would be a nice touch.

I also found a few broken links, which is not totally surprising, given the volume of them in this book.

None noticed in this review.

No objectionable content found - the authors have chosen inclusive examples wherever possible, while remaining realistic about subjects students might be researching.

Not all of the links to activities are self-describing (there are no plain URLs, but many of the activity links contain the same 'Open Activity in Web Browser' text, which would be confusing if a user was navigating with a screen reader.

The book is very comprehensive. The authors consistently explain concepts well and provide easy-to-understand examples that are approachable for the undergraduate audience. For example, the authors don’t just say, “narrow down your source,” they go through steps to narrow it down, walking students through the process. (p 9) Very thorough. They also spend a page and a half giving examples of “Regular Question” vs. “Research Question.” (p 13-14) This ensures that students will understand the difference. They also do well with explaining fact vs. option, objective vs. subjective, primary vs. secondary vs. tertiary sources, popular vs. professional vs. scholarly magazines, when to quote vs. paraphrase vs. summarize, and other concepts that are critical to performing research.

The book does not have an index. The table of contents is quite thorough and very useful in understanding the breakdown of the book or locating certain topics.

The book is error-free.

There are many digital examples in the text. As long as authors make updates as technology inevitably changes in the future, the book should remain relevant.

The book has a conversational tone that is connective, trustworthy, and approachable for the undergraduate audience. This makes it easy to read and easy to understand.

The book is very consistent with tone, and terminology.

In the introduction, the book encourages students to “jump around a bit in this guide to meet your needs.” (p 5). The book stays true to this idea. Students could read the book straight through, but it is well-designed for “jumping around.” The sections stand alone, and instructors could easily assign sections in the book out of order. This book could be used as the only textbook in a classroom, or an instructor could use these modules to supplement an existing textbook. Topics are easily found in the book thanks to an excellent table of contents, a clear organizational structure, and a great use of headers.

The book is well-organized and follows a logical structure. Individual topics are also well-organized. The authors break processes into step-by-step, making is easy for students to learn.

Great use of visual aids. For example, there is a chart on how to narrow down research topic (p 9), and a chart on the roles of resources in research (p 179). These items are great for visual learners, and they make the text come alive while emphasizing important concepts.

The book shares links to outside sources. This provides students that would like more information that is beyond the book with resources. It additionally provides students links to activities, such as one that asks them if a source is primary, secondary, or tertiary (p 34). On occasion, it links to outside companies, such as citation management software, news outlets, and social media, making the book a resource. In this way, the book utilizes the medium of a digital book.

The book is free of grammatical errors.

The book is culturally sensitive. The book is designed for Ohio University students. Examples given occasionally apply to Ohio, such as when the authors are providing examples of newspapers, they list two out of six that are from Ohio, including the campus newspaper (p 43) There is also a link to the OSU Libraries’ newspaper database (p 44), and when talking about citation management software, they mention the three that are available at OSU. It’s not a large enough issue that one should not use the book; it’s still easy to understand, but it is a limitation and worth mentioning to students.

I teach a 300-level English class on performing research and writing research papers. I plan to utilize this book next semester due to the excellent organization of modules, the approachable tone, and the great explanations and examples.

The book does an excellent job covering the subject, and even goes beyond what its title suggests, with chapters on writing and formulating an argument. The chapters on copyright and fair use are exceptional. However, it lacks both a glossary and an index. Some terms are defined in their appropriate chapters, but not all. Some students, particularly first-year or those who may be enrolled in developmental courses, would benefit greatly from a glossary. The activities, while appropriate for their contexts, are mixed in their effectiveness; some provide good feedback with clarification, but most offer little more than a smiley face for a correct answer or an “x” for a wrong answer with no other feedback.

For the most part, this book is accurate and unbiased, but one area where I noticed discrepancies is the chapter on citing sources. MLA released its 8th edition in April 2016, yet the examples provided are 7th edition. I also noticed errors in the example for APA; only the first word, proper nouns, and those following major punctuation marks are to be capitalized in article titles following APA formating guidelines. Regarding bias, the book is unbiased; however, I disagree with the discussion of news sources regarding mainstream versus non-mainstream (or mainline as used in the text); main-stream media includes "traditional" sources, e.g., television, newspapers, and radio, as opposed to online sources, especially social media. The authors’ inclusion of Fox News, a right-leaning national television news network, a contemporary of CBS, NBC, and ABC, as non-mainline rather than mainline shows bias, in my opinion. It’s difficult to find news from any news source, mainstream or not, right, left or center, that doesn’t have some bias or opinions in its reporting.

This textbook itself is written so that it will be relevant for a long time. However, there are some exceptions. The discussion of citation styles uses examples for MLA that reflect the 7th edition rather than the 8th, which was released in April 2016. The book covers this discrepancy somewhat with its tip regarding choosing a citation style, with its remarks that styles do change and its recommendation to check with one’s instructors. Another issue is the potential for link rot regarding external websites; in fact there are a few dead links in the text and activities already. A couple of online resources mentioned and linked to, IPL2 and the Statistical Abstracts of the US, have been retired for at least a couple of years, which makes me wonder about when the book was actually last reviewed edited.

The book is well-written, easy to read, conversational. Most technical language is defined and used appropriately.

This book is consistent in terms of its terminology and framework.

This book is extremely modular in its organization at the chapter level and within the chapters. It can be easily reordered to meet specific course or instructor needs. It does refer to other sections of the text, but these references are appropriate, emphasizing more in-depth information elsewhere in the book. Sections that are unique to OSU can be replaced/revised to make the text relevant to other institutions as needed.

It is well organized and reflects the processes and stages of research. While the research process is not linear, the topics are presented in a logical manner that guides students through the process. I did note that a couple of sections in chapter 7, on ethical use of sources don’t really seem to fit there, however. The paragraphs on page 118 discussing a lack of understanding of the materials and lack of time might fit better in other chapters.

While the online version works well, the PDF format has issues. Some of the in-text navigation links work (the TOC links) while others found throughout the text don’t, often giving an “error: unknown export format” message. There are also a few dead links in both the online and PDF formats, as well as in some of the online activities. Some links direct users to OSU Libraries’ resources, either their catalog or their licensed databases, but not all such links are clearly identified as such.

Grammatical Errors rating: 3

For the most part, this text is well-written, grammatically; however, it does have a few grammatical/typographical errors, possibly more than one might expect from a text of this length, and assuming that the author is most likely a committee rather than an individual, more eyes reviewing the text should catch such errors. There are also instances of tense inconsistencies, shifting from present to past in the same sentence. Two paragraphs on page 47, under “Finding Data in Articles . . .,” repeat the same four sentences verbatim in different order. This occurs again on page 88. While these are not grammatical errors, they are certainly editorial errors. Most of the online activities have typos, as well, more so than the textbook.

This textbook is not culturally insensitive or offensive.

I do like this book. I think it puts the topic in terms that students can readily use and understand. I'd even recommend the chapters on copyright and fair use to faculty! I do think that it could benefit from the inclusion of a glossary and an index, as well as regular and frequent review, especially in regards to the linked resources. The PDF version definitely needs revisions since it seems that most of the in-text referral links throughout the text don’t work. Since it is tailored to OSU’s library resources, any instruction librarian using the book can substitute content relevant to his/her institution; non-library faculty using the text can consult their own librarians for help with this.

The book is very comprehensive and even goes beyond what might be expected in this kind of textbook. Along with choosing and using sources, the authors include a section on making an argument. Topics are dealt with appropriately and the text employs tests and activities along the way. I found some of the activities were not particularly well designed and sometimes answers to questions were based on assumptions by the authors as to context that in real life may or may not be appropriate. For instance, they claim that the periodical/journal title "Coral Reefs" is a scholarly journal, but judging by the title alone in a real life exercise there is no way to know whether it is scholarly or popular in nature.

There could have been more discussion about context and how it defines whether a sources is primary, secondary or tertiary. '

What the this textbook does not have is any kind of index or glossary, which I found disappointing.

I did not find any instances of inaccuracies in the text. I did find, however, some assumptions in the text that were not always warranted. I took issue with the assumption that mainline news sources are objective (p. 42). It is very clear that news articles are often biased. I think telling students that mainline news sources are objective effectively disarms instead of promotes critical thinking by students doing research.

On page 126 there is a discussion about using quotations where the authors say that all quotes are to be put within quotation marks. This is not true of block quotes in MLA or APA style and they omit any mention of it.

This textbook should retain its relevancy for several years, but it will lose its effectiveness very soon, since many of the dozens and dozens of links in the text will surely break before long. In the short term the links are a great feature, but they do severely limit the longevity of the book. I also found them annoyingly pervasive.

It should also be noted that the MLA citation example on page 122 uses the outdated MLA 7th edition guidelines.

Overall, I thought the book was very clearly written and easy to follow. The one section I struggled reading was the section on sources and information need. It seemed to want much more editing and was often wordy and almost obscure.

I did not notice any lack of consistency in terminology or framework.

This is one the book's strengths. It was clearly organized into topics and subtopics which sometimes could be addressed in an order chosen by an instructor. There were, however, occasional self-references to earlier sections or previously used external sources.

Moving from the simpler aspects of choosing and evaluating sources to the more complex uses of them and how arguments are constructed made good sense.

Interface rating: 2

I found the interface to have significant problems. At least a dozen links would not work from the PDF text when opened in Firefox. I often got the message, "error: unknown export format." The links seemed to work when viewing the text online, however.

The textbook's usefulness outside of Ohio State is severely limited by the frequent use of sources only available through OSU student logins. The textbook was written for OSU students, but it really fails as a textbook for any other institution unless it is significantly modified.

I found a few missing punctuation marks, and only two missing or wrong words in sentences. For a textbook this long, that's very good.

The textbook used interesting and non-offensive examples.

While it's a good textbook for choosing and using information sources it suffers from being too specifically written for OSU students, as well as including an overabundance of links that will reduce its longevity. Not including any kind of index or glossary is also a drawback.

Ch. 1 has a great overview of regular versus research questions and the difference between qualitative and quantitative research. Ch. 2 covers primary, secondary, and tertiary sources as well as popular, professional, and scholarly. Ch. 3 includes a source plan (i.e. what do you need the sources for and what is your plan). Ch. 4 gives tips and hints for searching on a library database. Ch. 5 gives different search options, like the library or Google Scholar. Ch. 6 is all about evaluating the sources you find, including clues about sussing out bias and thoroughness, as well as discussing currency of topic. Ch. 7 discusses why you should cite sources. Ch. 8 discusses ways to cite sources. Ch. 9 is looking at argument as dialog and what is necessary in that exchange and a recommended order of components. Ch. 10 covers quoting, paraphrasing,and summarizing and signal phrases. Ch. 11, 12 are copyright and fair use. Ch. 13 covers the roles or research.

I will use Ch. 1 and 2 in my classes, as I think the breakdown of research is useful and clear. Ch. 3 also has useful imbedded tools that will help students plan; Ch. 4 and 5 might be used as references post-library visit. I will also use Ch. 6 and Ch. 10.

I think the information provided for distinguishing scholarly, popular, and professional is helpful and I hope the resources help students understand good, reliable sources a bit better. The same is true for searching for sources, and I think the sections on search engines and evaluation of sources are going to be quite useful.

While the information on copyright, fair use, and why and ways to cite sources is fine, I won't be using these for my English classes as I find them not as helpful or relevant.

I think the book is quite accurate in terms of information provided. They use sources that both I and my students use, so clearly the book is addressing real needs in the classroom. It also makes suggestions that reinforce the concepts our librarians share with the students and instructors, so I find this to be extremely helpful.

The book suggests Purdue OWL, a source I also use; however, I realized this year that OWL was behind in updating some of the MLA citation changes. So that's something maybe for the book authors to note or address when recommending websites.

With that said, I think the book covers key specifics like university library websites, Google Scholar, and search engines, in broad enough terms to keep it relevant. Also, the graphics are simple and not dated, and there is one drawing of the "outernet" that shows what social media, Youtube, etc. would look like in the "real, outer" world. This drawing is the only thing I saw that might be dated soon, but its point is still solid.

Very easy to read, clear terminology and explanation of terms, and lists are also provided to help break up each page's prose, which means the information is presented in a visually clear form as well.

I think the consistency of terminology as well as the scaffolding makes sense on the whole. I didn't seem places where the language changed or seemed to have several writers or definitions.

Perhaps one of the best parts of this book is how each chapter is contained, succinct, includes an activity, but still builds on and with the other chapters. Each chapter is stand-alone and clear and easy to read online, or if you chose to print it. The creators clearly had the online reader in mind, however, and the chapter lengths and fonts are comfortable.

Overall, I like the organization, specifically for chapters 10-6. I would change the order of the final chapters so that Ch. 9 and 10 come before Ch. 7, 8, 11, 12. I would also move Ch. 13 "The Roles of Research" to earlier in the book, perhaps around Ch. 3 or Ch. 6. If I use these materials, I will reorder some of the chapters for my class so that the scaffolding and explanations work a bit more side by side.

Again, comfortable, easy-to-read pages, simple graphics and the charts used are helpful and appropriate. I especially appreciated that the authors didn't use images that showed people or figures that could both date the book and also make students feel talked down to - I hate images like this and refuse to use textbooks that incorporate them, so kudos!

Additional resources are easy to access.

I wish the email option (for sending yourself a page) pulled up a screen in which I could type the email I wanted it sent to. Instead, it pulls up Messenger, which I don't use.

The Table of Contents didn't let me jump to the chapter when I pulled down the menu. Was that just my computer/browser?

Now, I didn't read through as though I was grading (it is winter break, after all!) but nothing jumped off the page. If something had, if there had been a mistake, I would still use the text; if there had been several, I would have considered abandoning it for class. However, the information is still so good I i might have told my students to find the grammar mistakes as part of an assignment just so that I could use the research parts still; however, I didn't not see any.

No, nothing. Perhaps if the authors include more examples for citations they could pull from culturally different sources then, but the material here was so broad in terms of textual sources it was in no way exclusive.

I will be using parts of this book in my English classes. Well done to the authors - a helpful, free supplement.

I noted a logical progression to all thirteen of the chapters. Students in upper-level classes would find the chapters on Fair Use and Copyright more significant in their academic studies.

The hyperlinks and the interactive elements of the book will be extremely appealing to students as well as being substantive.

The book still needs some work in this regard. Pronouns don't always agree with the antecedents, and I noted several shifts in voice in the text.

The text doesn't have any instances of cultural insensitivity, and I pay close attention to this aspect of textbooks when I peruse them for potential use in my courses.

A very comprehensive guide to the writing of the research paper. I've taught research writing for several years, and this book covers all the material I'd typically cover in a class. Previously I've not used a textbook in that class, but I'm teaching an online section this term and find that the book offers a very effective substitute for the lectured and activities I'd otherwise be presenting in class.

This text is accurate and up-to-date with the most recent developments and issues in the field.

This text is very much up-to-date. It shows an awareness of changing conventions in academic writing, and emphasizes the latest technological tools for researching and managing citations. It frequently links to outside resources, which could be problematic in the event those resources were removed or relocated, but in practice I never encountered such an issue.

Clarity is one of the book's strengths. It is written in clear, simple, and concise prose, resisting the kind of "academese" that is frequently employed in textbooks and gives students a false impression of what academic writing should look like. I found all of the content very easy to understand, and, although it's intended for slightly more advanced classes, accessible for Freshman writing students.

The text is highly consistent, both in terms of the terminology it employs, its organizational structure, and its systematic incorporation of tips, learning activities, and quizzes.

The book is divided into 13 chapters, each of which addresses particular aspects of research writing and can be employed on its own, or in conjunction with other related chapters. I found that assigning chapters in order was generally perfectly appropriate, although there was no issue with assigning the odd chapter out of order - links to previous or later content are provided where appropriate, so students can easily navigate to other relevant sections of the text.

This text is very nicely organized. It moves from the beginning stages of the pre-writing process - choosing a topic and identifying appropriate guiding questions - through the research to the writing of the paper itself. I found that the organizational structure of the text very closely mirrored the structure I use myself in teaching research writing. As such, adopting this text for the course (and adapting the course to the text) was a delightfully straightforward exercise.

The interface of the text is excellent. It is very easy to navigate, very attractive, and all tools work as intended. Some features are only available to those with Ohio State University log-ins, which yields a handful of frustrating moments, but in general I didn't find this to be a significant issue.

The text is error free and written in a simple, accessible, and engaging style. It's not merely an easy read, but one that effectively models clear and concise academic prose for writing students.

To the extent such issues come into play, the text is inclusive and culturally sensitive. The content of the text is mostly neutral on such issues - they simply tend not to come into play - but I was pleased to find a comprehensive chapter on the ethical use of sources, which introduces an ethical dimension to the research and writing process that many students may not anticipate or otherwise be prepared to navigate.

Overall I was quite pleased with this text. In my online section of Research Paper Writing, I have assigned nine of the thirteen chapters, and am very pleased with the breadth of content covered thereby. With one exception, I've been able to assign those chapters in the order they appear in the book, which simplified the planning process for myself, and offers a structure to the course that will be more readily apparent to my students as well. Late chapters on Copyrights Basics and Fair Use struck me as unnecessary and a little off topic, but it is of course easy to simply not assign those chapters, and since this is not a print book they have no bearing on materials costs.

For an online class like the one I am currently teaching, this is an excellent primary text. Even in a face-to-face class it could prove to be a very useful supplemental text. Normally I resist the use of supplemental texts in face-to-face classes, but since this one is free it is ideal for that purpose: instructors and students can simply rely on it to whatever extent feels useful.

This book is an excellent source for guiding undergraduate students through the research process, from understanding the purposes for doing research and writing a research question, to composing a thesis and contributing to a scholarly conversation. Students learn where and how to find relevant sources and how to evaluate and use them ethically. The main text is supplemented with links to useful resources, videos, worksheets, examples, and exercises. These are all high quality sources, making this a comprehensive resource for teaching information literacy and the research process. While no index or glossary is provided, terms are well defined within the text. Links are provided to other sections within the text where terms are further discussed.

The content is error-free, unbiased, and accurate. Ideas and concepts are in accordance with the Association of College and Research Libraries’ “Framework for Information Literacy for Higher Education,” with the exception of several small sections that could easily be clarified or adapted.

The opening section of Chapter 3 states that researchers should find sources in order to meet their information needs. However, it states that one information need is “to convince your audience that your answer is correct or, at least, the most reasonable answer.” This should be clarified for students so that they understand that they should start their research with an open mind as opposed to looking for sources which support their predetermined thesis.

The section “The Sources to Meet Needs” in Chapter 3 states that convincing one’s audience is an information need and that students should find sources based upon what their audience would be convinced by. Researchers should not choose their sources based upon what would convince their audience, but rather upon what sources best answer their research question. The most relevant and highest quality sources should not be omitted from the research process because the researcher does not think that his/her audience would be convinced by them. It is part of the researcher’s job to educate and convince his/her audience why the chosen sources and the research are relevant and of high quality.

Chapter 13 mentions briefly, “Putting your sources to work for you in these roles can help you write in a more powerful, persuasive way—to, in fact, win your argument.” It is very important for researchers to make convincing arguments through using quality sources, doing quality research, and presenting the information in an understandable way. Students should understand that the goal of scholarly conversation is not to “win” arguments, but rather to contribute to the world’s shared knowledge. While one argument may hold for a time, it will most likely be refined in some way by future researchers.

The main content of each chapter is current and does not contain terms that will soon be outdated. Specific examples and exercises are arranged separately from the main chapter text and can be updated independently. Some of the content discusses and links to Ohio State University Libraries databases which are unavailable to students at other institutions. While some of this knowledge is transferable, the specific information about these databases is unique to OSU Libraries. It would be useful if this information could be generalized in the main flow of the text so that it would be applicable for students at other institutions.

This text is very readable and easy to understand. Concepts are explained clearly. Exercises and examples are provided to help students grasp each new concept. It is written in a casual tone that appears to make an effort to put its readers at ease while giving solid information about how to complete research and writing assignments successfully.

The terminology used in this book and its framework are consistent. Each chapter, chapter sections, examples, and exercises are organized in a consistent manner throughout the book, making it easy to follow. Students can refer to specific sections of the book or read it straight through. Because links are provided to sections of the book where important terms are defined or discussed further, students can easily jump to relevant sections of the book.

The book is divided into chapters and subsections which lead the reader seamlessly and logically through the research process. The book could easily be assigned to be read linearly, but it would also work well for instructors to assign specific chapters as applicable to the course content.

This book takes students through the research process in logical steps, from choosing and refining research questions, to producing and sharing what they have learned. For students who are unfamiliar with the research process, it would be most useful to read the book linearly as each chapter prepares students for future chapters.

This text is easy to navigate in both the PDF and online versions. Images are clear. There are currently no broken links. The contents in the PDF version could be made clearer by making a greater distinction between the main chapter and chapter section titles.

The text has negligible grammatical errors.

This text is not culturally insensitive or offensive.

I highly recommend this book for teaching information literacy and the research process to undergraduates.

This textbook does not include an index or glossary but is full-text searchable, returning a an easy to read and access menu of clickable search results to take readers directly to the desired information. In addition, an expandable Table of Contents for the book is available as a tab so that readers can view an overview of topics and jump to other sections at any time. This textbook offers a review of research methods that is certainly comprehensive. Instructors will likely find that individual sections, rather than the whole work, are most useful in planning lessons and constructing student assignments in research based and writing intensive courses at the undergraduate level.

This textbook is accurate in its representation of research methods and of the reasoning behind these approaches. In addition, details about citation styles, and search tools, seem error-free. Treatments of the more complex aspects of research, such as constructing an argument, are unbiased and thorough.

The textbook should be useful to students and instructors for some time. It should be noted, however, that research software and citation styles are updated, though infrequently. Thus, the video walkthroughs of particular databases, for example, may be obsolete or misleading after some time.

This textbook is remarkably lucid and approachable for undergraduate readers. Discussions of complex ideas are illustrated with useful graphics that readers and instructors will find particularly helpful. The video walkthroughs are perhaps the most attractive illustrations for instructors. These guides will be appealing and easy to use for students intimidated by large databases and their idiosyncrasies.

The textbook is immanently usable. It is consistent in its tone as well as in its use of terms.

It is clear that this textbook has been designed with modularity in mind. Individual sections will be more useful than others, depending on the type and level of the class. In addition, sections can easily be assigned at different points over the course of a semester. For example, sections might be assigned at intervals that reflect the stages of the development of undergraduate student’s independent research paper. The section on formulating research questions might appear early in the semester, the section on citation styles toward the end.

The organization of the book reflects the stages of research. This means that navigating the textbook will be intuitive.

Navigating this textbook will be intuitive, the Table of Contents tab makes moving between sections very easy.

Readers will find the textbook free of simple typos and errors.

Readers will find the textbook inclusive. Some readers may find that the attempt made in the textbook to speak to research in the humanities, social sciences and sciences has meant that discussions can be vague at times but this is to be expected in a textbook on this topic aimed at a broad range of readers and researchers.

This text is a comprehensive review of the various types of sources one might need to complete a research project or paper. The book begins with a clear explanation of how to formulate a research question, while the majority of the chapters focus on finding and evaluating sources. The topics in this text are well-chosen and reflect several aspects of academic writing in which beginning researchers might struggle, such as how to do a precision search, understanding biased versus unbiased sources, and how to decide between quoting or paraphrasing. This book is written at a level that undergraduates should easily be able to comprehend, while the content of the chapters gets increasingly detailed and complex throughout the book. There is no index or glossary at the back of the book, but there is a very complete table of contents at the beginning of the text. Readers might find it useful if the chapter titles in the table of contents were in bold, as the detailed breakdown of sections—while helpful—can be overwhelming when one is looking for the main categories of the book.

The text provides helpful and unbiased examples for how to do research in many different areas. The practice activities relate quite well to the content of the chapters, although some links do not work. One of the strengths of the text is its applicability in a general sense to many different types of research.

In most chapters the information is kept very general, allowing the text to enjoy relative longevity, as the process of how to conduct academic research, cite quotes, etc., likely will not change drastically in the near future. For example, in the section on databases, different types of databases are explained, but the author does not reference many specific databases to which students may or may not have access. With an understanding of the concept, students then are equipped to find the databases that pertain to their field and that are offered by their institutions. There are several references to Ohio State throughout the text that will not be helpful to all readers, but they do not impede the reader’s comprehension of the text.

It is a very readable text, written at a level that makes it easily accessible to undergraduate students. The author has avoided jargon that would be confusing to the readers.

Even though the book gives examples of various types of research and sources, it maintains a high level of consistency throughout.

The chapters are clearly divided in a way that allows the reader the option to skip between chapters or to read the chapters in succession. This text could be put to a variety of uses within the classroom. As an instructor, one could use it as a primary text for a Research Methods or Composition class. One could also suggest that students read only certain sections in a class that was not primarily focused on the writing of research papers but that had a research component. This text is a valuable how-to manual that students can reference throughout their academic journey.

The text has a logical organization and flow. The book transitions from more basic information at the beginning to more specialized knowledge in later chapters, allowing students to gradually become more immersed in the topic. The structure permits students to read the text from cover to cover, or to read only the information and chapters about which they are curious. The activities serve as good checkpoints to assess students’ knowledge and break up longer readings.

The interface of the text is easy to manage and does not distract from the content. The placement and accessibility of the activities provide quick and easy checks to assess whether students have understood the concepts of the chapters. The images support the text and are linked closely to the message.

There are few grammatical errors in this text.

The text is not culturally insensitive or offensive. Like many textbooks, it could be more intentional in its inclusion of a variety of races, ethnicities, and backgrounds, perhaps in the examples or practice activities.

Reviewed by Dr. William Vann, Information Studies Faculty, Minneapolis Community and Technical College on 12/5/16

While there is neither a back-of-the-book index nor a compiled glossary in this outstanding textbook (key terms are defined, however, throughout the chapters), one cannot deny its comprehensiveness. In fact, this text covers so much ground it is unlikely to be used in its entirety for any single college course. Information literacy and research skills courses will find the first eight chapters to be a robust introduction to their subject matter, replete with interactive activities and auto-graded assessments. Composition courses engaged in research-based writing will likely work through the first eight chapters selectively, but then dwell on chapters nine and ten on argument formation and writing. Such courses may also benefit from the excellent chapter thirteen on Joseph Bizup's BEAM method of deploying research sources in scholarly communication. Chapters eleven and twelve on copyright and fair use, respectively, are likely to be used only by advanced undergraduates, faculty, and professional librarians, but they do serve as a handy reference nonetheless.

All of the chapters of this textbook contain authoritative and accurate information, in line with national information literacy standards and sound pedagogical methods for composition and critical thinking. The only section of the text I took issue with was the "Fact or Opinion" part of the second chapter, where the authors try to distinguish between fact, opinion, subjective information, and objective information. The authors' attempt results in claims like "the death penalty is wrong" being rendered as opinions, while claims like "women should stock up on calcium to ensure strong bones" are judged to be subjective information. Facts and objective information are superior, on this way of thinking, because they are the result of research studies, particularly empirical, quantitative ones.

I suspect that this way of drawing the distinction would do little to challenge the naive relativism most undergraduates bring to the classroom. (How many of us, when analyzing a text with beginning undergraduates, have had to entertain the question "Isn't that just the author's opinion though?") A better approach would be to talk about claims that are empirically justified (facts), claims that are justified, but not empirically (value judgments - "x is wrong", prescriptive claims - "women should do x"), and claims that are not adequately justified by any means (opinions). In this way, answering a research question like "Is the death penalty unjust?" is not merely an exercise in subjective opinion-making, but rather an exploration of reasoned argumentation, only some of which may be empirical or based on research studies.

The text is current and will likely be so for some time. Examples, activities, and tips are marked off from the main chapter prose, so will be easy to refresh when necessary.

There is no lack of technical terms in the world of information studies, but this textbook does a fine job of providing definitions where appropriate in each chapter. Concepts and methods are explained in context, and illustrative, easy-to-follow examples adorn each chapter.

The only area of the text that falls a little short on clarity is the interactive activities. These are usually multiple choice or matching questions, but some of the word choice in questions left this reader confused, and in some cases the instructions could have been more explicit.

Being authored by committee, we might expect this textbook to suffer in the consistency category. Yet it does not, thanks again to the fine editing job by Cheryl Lowry. Perhaps the book's provenance as a series of online tutorials put together by librarians and faculty at OSU is partly responsible for this.

As the authors suggest on the first page, the research process isn't always linear. So reading a text modeled on the research process oughtn't to be a straightforward chapter-by-chapter march either. Consequently, faculty and students can comfortably read this text selectively and skip chapters as needed. For the most holistic understanding of the research process, however, it would be sensible to work through at least chapters one through eight in their entirety.

I appreciate how the text's organization mirrors the research process itself. The first chapter takes on research questions, exactly where student researchers need to begin their projects. Subsequent chapters explore types of information sources, how to find and evaluate them, and finally how to deploy them in a well-argued scholarly product. The writing in each chapter is clear and crisp, with important concepts amplified by colorful visualizations.

As mentioned above, the chapters on copyright and fair use which occur near the end of the book feel like a logical interruption to the book's flow, and they might well fit more comfortably as appendices for occasional reference by advanced undergraduates, faculty, and librarians.

The "look and feel" of this textbook is clean and very intuitive to navigate through. The design strikes a pleasing balance between prose, graphics, and special formatting features like the explanatory, grey-background "TIPS" found in each chapter. Subheadings, bulleted and ordered lists, and judicious font choices make the text easy to read in all its online file formats.

One weakness of the interface is that several of the linked activities point to OSU Libraries' resources, thus requiring OSU authentication to be accessed. While it is understandable that the authors wanted to include their libraries' proprietary information sources in the activities - these are the sources their students and faculty will be using in actual practice, after all - this obviously makes this text less of an "open" textbook. Those outside of the OSU community who would like to adopt this textbook will therefore have to come up with their own replacement activities in such cases, or do without.

A few of the links in the text did lead me to a curious OSU server error message: "Error: Unknown export format", but I expect these links will be repaired as they are reported to the authors.

This textbook has clearly been edited with careful eyes by Cheryl Lowry, as grammatical errors are few to none. The grammatical hygiene of the text can probably also be attributed to its collective authorship - over a dozen librarians and faculty of the Ohio State University Libraries developed the content, which was born out of a series of online tutorials.

This textbook is culturally relevant in its use of examples and depictions of college students.

This text is a substantial contribution to the open textbook movement, and its quality easily meets or exceeds anything comparable in the commercial publishing arena. Highly recommended.

The book provides a thorough introduction and how to regarding sources in academic writing. With the exception of the first chapter on writing research questions, the rest of the book is focused on sources, which is relevant for any type of academic writing not just research papers. The information is relevant across disciplines and readable to a wide audience. It is clearly written for and geared towards undergraduate students, particularly from Ohio State University. The index is detailed making it easy to locate specific information and includes hyperlinks for clear navigation. A slightly altered index format would make the chapter topics more readily available and accessed. All subjects and chapters are aligned rather than clearly indicating each of the chapters found within the text.

Content throughout the book is accurate and clearly written. There does not appear to bias in reading the material. The book includes numerous resources linked throughout the text, however some are no longer active resulting in error messages.

Due to the significant number of links throughout the book, it is likely updates will be necessary on a consistent basis. These links are extremely beneficial, so ensuring they are accurate and up to date is essential to the content of this book. Much of the book reads as a "how to" regarding sources, so although practices for scholarly writing will likely not become obsolete the sources and technology used to locate the sources will evolve.

The informal tone of the text is engaging and applicable for the intended audience. The writers are aware of their audience, avoiding technical jargon. Also, throughout the book they provide numerous examples, resources, activities, and tips to provide insight and relevancy to students.

The structure of the book is clear and well organized with each chapter providing scaffolding for the next. Although the text is internally consistent regarding terminology there are formatting differences between and within some chapters. Blue boxes throughout the text contain tips, examples, answers, etc. Organization, readability, and consistency could be improved if these were constant throughout the text similar to the presentation of activities in the text.

Sections of the book could be easily assigned and read in isolation. Subsections of material are clearly marked and chapters are presented in organized fashion with clear delineation between segments. The inclusion of numerous activities, examples, resources, and tips improve modularity.

The book is created as a tool for students completing academic writing and follows this course. Topics contained in the book are presented in a clear and logical structure. As mentioned above, with exception of the first chapter, the material is relevant to all undergraduate academic writing, not just research.

The layout and display work well as a PDF or electronic book. Numerous visuals are included throughout and are free of distortion or other distracting or confusing issues. As mentioned above, the index could be improved by clearly articulating the subheadings as within a chapter.

The book contains minimal to no grammatical errors.

The book is not culturally insensitive or offensive in any way.

Some sections of the book are specific to Ohio State University potentially limiting its relevancy and audience in specific chapters or sections.

Bibliography

A citation is a formal reference to a published or unpublished source that you consulted and obtained information from while writing your research paper. It refers to a source of information that supports a factual statement, proposition, argument, or assertion or any quoted text obtained from a book, article, web site, or any other type of material . In-text citations are embedded within the body of your paper and use a shorthand notation style that refers to a complete description of the item at the end of the paper. Materials cited at the end of a paper may be listed under the heading References, Sources, Works Cited, or Bibliography. Rules on how to properly cite a source depends on the writing style manual your professor wants you to use for the class [e.g., APA, MLA, Chicago, Turabian, etc.]. Note that some disciplines have their own citation rules [e.g., law].

Reasons for Citing Your Sources

Reasons for Citing Sources in Your Research Paper

English scientist, Sir Isaac Newton, once wrote, "If I have seen further, it is by standing on the shoulders of giants.”* Citations support learning how to "see further" through processes of intellectual discovery, critical thinking, and applying a deliberate method of navigating through the scholarly landscape by tracking how cited works are propagated by scholars over time and the subsequent ways this leads to the devarication of new knowledge.

Listed below are specific reasons why citing sources is an important part of doing good research.

Shows the reader where to find more information . Citations help readers expand their understanding and knowledge about the issues being investigated. One of the most effective strategies for locating authoritative, relevant sources about a research problem is to review materials cited in studies published by other authors. In this way, the sources you cite help the reader identify where to go to examine the topic in more depth and detail.
Increases your credibility as an author . Citations to the words, ideas, and arguments of scholars demonstrates that you have conducted a thorough review of the literature and, therefore, you are reporting your research results or proposing recommended courses of action from an informed and critically engaged perspective. Your citations offer evidence that you effectively contemplated, evaluated, and synthesized sources of information in relation to your conceptualization of the research problem.
Illustrates the non-linear and contested nature of knowledge creation . The sources you cite show the reader how you characterized the dynamics of prior knowledge creation relevant to the research problem and how you managed to effectively identify the contested relationships between problems and solutions proposed among scholars. Citations don't just list materials used in your study, they tell a story about how prior knowledge-making emerged from a constant state of creation, renewal, and transformation.
Reinforces your arguments . Sources cited in your paper provide the evidence that readers need to determine that you properly addressed the “So What?” question. This refers to whether you considered the relevance and significance of the research problem, its implications applied to creating new knowledge, and its importance for improving practice. In this way, citations draw attention to and support the legitimacy and originality of your own ideas and assertions.
Demonstrates that you "listened" to relevant conversations among scholars before joining in . Your citations tell the reader where you developed an understanding of the debates among scholars. They show how you educated yourself about ongoing conversations taking place within relevant communities of researchers before inserting your own ideas and arguments. In peer-reviewed scholarship, most of these conversations emerge within books, research reports, journal articles, and other cited works.
Delineates alternative approaches to explaining the research problem . If you disagree with prior research assumptions or you believe that a topic has been understudied or you find that there is a gap in how scholars have understood a problem, your citations serve as the source materials from which to analyze and present an alternative viewpoint or to assert that a different course of action should be pursued. In short, the materials you cite serve as the means by which to argue persuasively against long-standing assumptions promulgated in prior studies.
Helps the reader understand contextual aspects of your research . Cited sources help readers understand the specific circumstances, conditions, and settings of the problem being investigated and, by extension, how your arguments can be fully understood and assessed. Citations place your line of reasoning within a specific contextualized framework based on how others have studied the problem and how you interpreted their findings in support of your overall research objectives.
Frames the development of concepts and ideas within the literature . No topic in the social and behavioral sciences rests in isolation from research that has taken place in the past. Your citations help the reader understand the growth and transformation of the theoretical assumptions, key concepts, and systematic inquiries that emerged prior to your engagement with the research problem.
Underscores sources that were most important to you . Your citations represent a set of choices made about what you determined to be the most important sources for understanding the topic. They not only list what you discovered, but why it matters and how the materials you chose to cite fit within the broader context of your research design and arguments. As part of an overall assessment of the study’s validity and reliability , the choices you make also helps the reader determine what research may have been excluded.
Provides evidence of interdisciplinary thinking . An important principle of good research is to extend your review of the literature beyond the predominant disciplinary space where scholars have examined a topic. Citations provide evidence that you have integrated epistemological arguments, observations, and/or the methodological strategies from other disciplines into your paper, thereby demonstrating that you understand the complex, interconnected nature of contemporary research topics.
Supports critical thinking and independent learning . Evaluating the authenticity, reliability, validity, and originality of prior research is an act of interpretation and introspective reasoning applied to assessing whether a source of information will contribute to understanding the problem in ways that are persuasive and align with your overall research objectives. Reviewing and citing prior studies represents a deliberate act of critically scrutinizing each source as part of your overall assessment of how scholars have confronted the research problem.
Honors the achievements of others . As Susan Blum recently noted,** citations not only identify sources used, they acknowledge the achievements of scholars within the larger network of research about the topic. Citing sources is a normative act of professionalism within academe and a way to highlight and recognize the work of scholars who likely do not obtain any tangible benefits or monetary value from their research endeavors.

Structure and Writing Style

Referencing your sources means systematically showing what information or ideas you acquired from another author’s work, and identifying where that information come from . You must cite research in order to do research, but at the same time, you must delineate what are your original thoughts and ideas and what are the thoughts and ideas of others. Citations help achieve this. Procedures used to cite sources vary among different fields of study. If not outlined in your course syllabus or writing assignment, always speak with your professor about what writing style for citing sources should be used for the class because it is important to fully understand the citation style to be used in your paper, and to apply it consistently. If your professor defers and tells you to "choose whatever you want, just be consistent," then choose the citation style you are most familiar with or that is appropriate to your major [e.g., use Chicago style if you are majoring in history; use APA if its an education course; use MLA if it is literature or a general writing course].

GENERAL GUIDELINES

1. Are there any reasons I should avoid referencing other people's work? No. If placed in the proper context, r eferencing other people's research is never an indication that your work is substandard or lacks originality. In fact, the opposite is true. If you write your paper without adequate references to previous studies, you are signaling to the reader that you are not familiar with the literature on the topic, thereby, undermining the validity of your study and your credibility as a researcher. Including references in academic writing is one of the most important ways to demonstrate your knowledge and understanding of how the research problem has been addressed. It is the intellectual packaging around which you present your thoughts and ideas to the reader.

2. What should I do if I find out that my great idea has already been studied by another researcher? It can be frustrating to come up with what you believe is a great topic only to find that it's already been thoroughly studied. However, do not become frustrated by this. You can acknowledge the prior research by writing in the text of your paper [see also Smith, 2002], then citing the complete source in your list of references. Use the discovery of prior studies as an opportunity to demonstrate the significance of the problem being investigated and, if applicable, as a means of delineating your analysis from those of others [e.g., the prior study is ten years old and doesn't take into account new variables]. Strategies for responding to prior research can include: stating how your study updates previous understandings about the topic, offering a new or different perspective, applying a different or innovative method of data gathering, and/or describing a new set of insights, guidelines, recommendations, best practices, or working solutions.

3. What should I do if I want to use an adapted version of someone else's work? You still must cite the original work. For example, you use a table of statistics from a journal article published in 1996 by author Smith, but you have altered or added new data to it. Reference the revised chart, such as, [adapted from Smith, 1996], then cite the complete original source in your list of references. You can also use other terms in order to specify the exact relationship between the original source and the version you have presented, such as, "based on data from Smith [1996]...," or "summarized from Smith [1996]...." Citing the original source helps the reader locate where the information was first presented and under what context it was used as well as to evaluate how effectively you applied it to your own research.

4. What should I do if several authors have published very similar information or ideas? You can indicate that the topic, idea, concept, or information can be found in the works of others by stating something similar to the following example: "Though many scholars have applied rational choice theory to understanding economic relations among nations [Smith, 1989; Jones, 1991; Johnson, 1994; Anderson, 2003], little attention has been given to applying the theory to examining the influence of non-governmental organizations in a globalized economy." If you only reference one author or only the most recent study, then your readers may assume that only one author has published on this topic, or more likely, they will conclude that you have not conducted a thorough review of the literature. Referencing all relevant authors of prior studies gives your readers a clear idea of the breadth of analysis you conducted in preparing to study the research problem. If there has been a significant number of prior studies on the topic [i.e., ten or more], describe the most comprehensive and recent works because they will presumably discuss and reference the older studies. However, note in your review of the literature that there has been significant scholarship devoted to the topic so the reader knows that you are aware of the numerous prior studies.

5. What if I find exactly what I want to say in the writing of another researcher? In the social sciences, the rationale in duplicating prior research is generally governed by the passage of time, changing circumstances or conditions, or the emergence of variables that necessitate new investigations . If someone else has recently conducted a thorough investigation of precisely the same research problem that you intend to study, then you likely will have to revise your topic, or at the very least, review this literature to identify something new to say about the problem. However, if it is someone else's particularly succinct expression, but it fits perfectly with what you are trying to say, then you can quote from the author directly, referencing the source. Identifying an author who has made the exact same point that you want to make can be an opportunity to add legitimacy to, as well as reinforce the significance of, the research problem you are investigating. The key is to build on that idea in new and innovative ways. If you are not sure how to do this, consult with a librarian .

6. Should I cite a source even if it was published long ago? Any source used in writing your paper should be cited, regardless of when it was written. However, in building a case for understanding prior research about your topic, it is generally true that you should focus on citing more recently published studies because they presumably have built upon the research of older studies. When referencing prior studies, use the research problem as your guide when considering what to cite. If a study from forty years ago investigated the same topic, it probably should be examined and considered in your list of references because the research may have been foundational or groundbreaking at the time, even if its findings are no longer relevant to current conditions or reflect current thinking [one way to determine if a study is foundational or groundbreaking is to examine how often it has been cited in recent studies using the "Cited by" feature of Google Scholar ]. However, if an older study only relates to the research problem tangentially or it has not been cited in recent studies, then it may be more appropriate to list it under further readings .

7. Can I cite unusual and non-scholarly sources in my research paper? The majority of the citations in a research paper should be to scholarly [a.k.a., academic; peer-reviewed] studies that rely on an objective and logical analysis of the research problem based on empirical evidence that reliably supports your arguments. However, any type of source can be considered valid if it brings relevant understanding and clarity to the topic. This can include, for example, non-textual elements such as photographs, maps, or illustrations. A source can include materials from special or archival collections, such as, personal papers, manuscripts, business memorandums, the official records of an organization, or digitized collections. Citations can also be to unusual items, such as, an audio recording, a transcript from a television news program, a unique set of data, or a social media post. The challenge is knowing how to cite unusual and non-scholarly sources because they often do not fit within standard citation rules like books or journal articles. Given this, consult with a librarian if you are unsure how to cite a source.

NOTE: In any academic writing, you are required to identify which ideas, facts, thoughts, concepts, or declarative statements are yours and which are derived from the research of others. The only exception to this rule is information that is considered to be a commonly known fact [e.g., "George Washington was the first president of the United States"] or a statement that is self-evident [e.g., "Australia is a country in the Global South"]. Appreciate, however, that any "commonly known fact" or self-evidencing statement is culturally constructed and shaped by specific social and aesthetical biases . If you have any doubt about whether or not a fact is considered to be widely understood knowledge, provide a supporting citation, or, ask your professor for clarification about whether the statement should be cited.

Other Citation Research Guides

The following USC Libraries research guide can help you properly cite sources in your research paper:

Citation Guide

The following USC Libraries research guide offers basic information on using images and media in research:

Listed below are particularly well-done and comprehensive websites that provide specific examples of how to cite sources under different style guidelines.

Purdue University Online Writing Lab
Southern Cross University Harvard Referencing Style
University of Wisconsin Writing Center

This is a useful guide concerning how to properly cite images in your research paper.

Colgate Visual Resources Library, Citing Images

This guide provides good information on the act of citation analysis, whereby you count the number of times a published work is cited by other works in order to measure the impact of a publication or author.

Measuring Your Impact: Impact Factor, Citation Analysis, and other Metrics: Citation Analysis [Sandy De Groote, University of Illinois, Chicago]

Automatic Citation Generators

The links below lead to systems where you can type in your information and have a citation compiled for you. Note that these systems are not foolproof so it is important that you verify that the citation is correct and check your spelling, capitalization, etc. However, they can be useful in creating basic types of citations, particularly for online sources.

BibMe -- APA, MLA, Chicago, and Turabian styles
DocsCite -- for citing government publications in APA or MLA formats
EasyBib -- APA, MLA, and Chicago styles
Son of Citation Machine -- APA, MLA, Chicago, and Turabian styles

NOTE: Many companies that create the research databases the USC Libraries subscribe to, such as ProQuest , include built-in citation generators that help take the guesswork out of how to properly cite a work. When available, you should always utilize these features because they not only generate a citation to the source [e.g., a journal article], but include information about where you accessed the source [e.g., the database].

Research Help

Need more research help? We're here for you.

Reference materials provide well-researched information—for example, facts, definitions, histories, overviews of a topic, statistics—on a large subject area (e.g., sociology or dance) or for a type of data (e.g., biographies or directories). They pack lots of information into one easy-to-find place, and support student research in a number of ways:

Quick access to simple, reliable, factual information in sources such as dictionaries, polls, and biographies.
General overviews and introductions to fields and terms you may not be familiar with in sources such as encyclopedias and topical guidebooks.
Referral to additional information sources that offer more detail or lead to journal articles and other kinds of materials, such as subject-specific indexes and encyclopedias.

Many reference works are available online and are accessible through links from the Library Catalog and from subject or course guides, but many valuable reference resources are still available only in print. Because print-only reference books are in high demand, they are kept in the separate, non-circulating Reference collection in most UCLA libraries.

To unlock the content of the Library's extensive reference collections, try searching the source below.

UCLA students, faculty, and staff can access these sites from off-campus using either the UCLA VPN Client or Bruin Online Proxy Server . If you need help setting up your computer, contact the UCLA IT Support Center at (310) 267-4357 or [email protected] . They answer the phone 24/7 and are very helpful.

NOTE: All campus wireless networks ( eduroam, UCLA_WIFI or UCLA_WEB ) provide access to online subscription content. If you are using a Mac, you may need to use Chrome or Firefox , not Safari , to read some of the pdf material.

Reference List: Common Reference List Examples

Article (with doi).

Alvarez, E., & Tippins, S. (2019). Socialization agents that Puerto Rican college students use to make financial decisions. Journal of Social Change , 11 (1), 75–85. https://doi.org/10.5590/JOSC.2019.11.1.07

Laplante, J. P., & Nolin, C. (2014). Consultas and socially responsible investing in Guatemala: A case study examining Maya perspectives on the Indigenous right to free, prior, and informed consent. Society & Natural Resources , 27 , 231–248. https://doi.org/10.1080/08941920.2013.861554

Use the DOI number for the source whenever one is available. DOI stands for "digital object identifier," a number specific to the article that can help others locate the source. In APA 7, format the DOI as a web address. Active hyperlinks for DOIs and URLs should be used for documents meant for screen reading. Present these hyperlinks in blue and underlined text (the default formatting in Microsoft Word), although plain black text is also acceptable. Be consistent in your formatting choice for DOIs and URLs throughout your reference list. Also see our Quick Answer FAQ, "Can I use the DOI format provided by library databases?"

Jerrentrup, A., Mueller, T., Glowalla, U., Herder, M., Henrichs, N., Neubauer, A., & Schaefer, J. R. (2018). Teaching medicine with the help of “Dr. House.” PLoS ONE , 13 (3), Article e0193972. https://doi.org/10.1371/journal.pone.0193972

For journal articles that are assigned article numbers rather than page ranges, include the article number in place of the page range.

For more on citing electronic resources, see  Electronic Sources References .

Article (Without DOI)

Found in a common academic research database or in print.

Casler , T. (2020). Improving the graduate nursing experience through support on a social media platform. MEDSURG Nursing , 29 (2), 83–87.

If an article does not have a DOI and you retrieved it from a common academic research database through the university library, there is no need to include any additional electronic retrieval information. The reference list entry looks like the entry for a print copy of the article. (This format differs from APA 6 guidelines that recommended including the URL of a journal's homepage when the DOI was not available.) Note that APA 7 has additional guidance on reference list entries for articles found only in specific databases or archives such as Cochrane Database of Systematic Reviews, UpToDate, ProQuest Dissertations and Theses Global, and university archives. See APA 7, Section 9.30 for more information.

Found on an Open Access Website

Eaton, T. V., & Akers, M. D. (2007). Whistleblowing and good governance. CPA Journal , 77 (6), 66–71. http://archives.cpajournal.com/2007/607/essentials/p58.htm

Provide the direct web address/URL to a journal article found on the open web, often on an open access journal's website. In APA 7, active hyperlinks for DOIs and URLs should be used for documents meant for screen reading. Present these hyperlinks in blue and underlined text (the default formatting in Microsoft Word), although plain black text is also acceptable. Be consistent in your formatting choice for DOIs and URLs throughout your reference list.

Weinstein, J. A. (2010). Social change (3rd ed.). Rowman & Littlefield.

If the book has an edition number, include it in parentheses after the title of the book. If the book does not list any edition information, do not include an edition number. The edition number is not italicized.

American Nurses Association. (2015). Nursing: Scope and standards of practice (3rd ed.).

If the author and publisher are the same, only include the author in its regular place and omit the publisher.

Lencioni, P. (2012). The advantage: Why organizational health trumps everything else in business . Jossey-Bass. https://amzn.to/343XPSJ

As a change from APA 6 to APA 7, it is no longer necessary to include the ebook format in the title. However, if you listened to an audiobook and the content differs from the text version (e.g., abridged content) or your discussion highlights elements of the audiobook (e.g., narrator's performance), then note that it is an audiobook in the title element in brackets. For ebooks and online audiobooks, also include the DOI number (if available) or nondatabase URL but leave out the electronic retrieval element if the ebook was found in a common academic research database, as with journal articles. APA 7 allows for the shortening of long DOIs and URLs, as shown in this example. See APA 7, Section 9.36 for more information.

Chapter in an Edited Book

Poe, M. (2017). Reframing race in teaching writing across the curriculum. In F. Condon & V. A. Young (Eds.), Performing antiracist pedagogy in rhetoric, writing, and communication (pp. 87–105). University Press of Colorado.

Include the page numbers of the chapter in parentheses after the book title.

Christensen, L. (2001). For my people: Celebrating community through poetry. In B. Bigelow, B. Harvey, S. Karp, & L. Miller (Eds.), Rethinking our classrooms: Teaching for equity and justice (Vol. 2, pp. 16–17). Rethinking Schools.

Also include the volume number or edition number in the parenthetical information after the book title when relevant.

Freud, S. (1961). The ego and the id. In J. Strachey (Ed.), The standard edition of the complete psychological works of Sigmund Freud (Vol. 19, pp. 3-66). Hogarth Press. (Original work published 1923)

When a text has been republished as part of an anthology collection, after the author’s name include the date of the version that was read. At the end of the entry, place the date of the original publication inside parenthesis along with the note “original work published.” For in-text citations of republished work, use both dates in the parenthetical citation, original date first with a slash separating the years, as in this example: Freud (1923/1961). For more information on reprinted or republished works, see APA 7, Sections 9.40-9.41.

Classroom Resources

Citing classroom resources.

If you need to cite content found in your online classroom, use the author (if there is one listed), the year of publication (if available), the title of the document, and the main URL of Walden classrooms. For example, you are citing study notes titled "Health Effects of Exposure to Forest Fires," but you do not know the author's name, your reference entry will look like this:

Health effects of exposure to forest fires [Lecture notes]. (2005). Walden University Canvas. https://waldenu.instructure.com

If you do know the author of the document, your reference will look like this:

Smith, A. (2005). Health effects of exposure to forest fires [PowerPoint slides]. Walden University Canvas. https://waldenu.instructure.com

A few notes on citing course materials:

[Lecture notes]
[Course handout]
[Study notes]
It can be difficult to determine authorship of classroom documents. If an author is listed on the document, use that. If the resource is clearly a product of Walden (such as the course-based videos), use Walden University as the author. If you are unsure or if no author is indicated, place the title in the author spot, as above.
If you cannot determine a date of publication, you can use n.d. (for "no date") in place of the year.

Note: The web location for Walden course materials is not directly retrievable without a password, and therefore, following APA guidelines, use the main URL for the class sites: https://class.waldenu.edu.

Citing Tempo Classroom Resources

Clear author:

Smith, A. (2005). Health effects of exposure to forest fires [PowerPoint slides]. Walden University Brightspace. https://mytempo.waldenu.edu

Unclear author:

Health effects of exposure to forest fires [Lecture notes]. (2005). Walden University Brightspace. https://mytempo.waldenu.edu

Dictionary Entry

Merriam-Webster. (n.d.). Leadership. In Merriam-Webster.com dictionary . Retrieved May 28, 2020, from https://www.merriam-webster.com/dictionary/leadership

When constructing a reference for an entry in a dictionary or other reference work that has no byline (i.e., no named individual authors), use the name of the group—the institution, company, or organization—as author (e.g., Merriam Webster, American Psychological Association, etc.). The name of the entry goes in the title position, followed by "In" and the italicized name of the reference work (e.g., Merriam-Webster.com dictionary , APA dictionary of psychology ). In this instance, APA 7 recommends including a retrieval date as well for this online source since the contents of the page change over time. End the reference entry with the specific URL for the defined word.

Note that for citations, include only the year: Clay (2008). For magazine articles retrieved from a common academic research database, leave out the URL. For magazine articles from an online news website that is not an online version of a print magazine, follow the format for a webpage reference list entry.

Newspaper Article (Retrieved Online)

Baker, A. (2014, May 7). Connecticut students show gains in national tests. New York Times . http://www.nytimes.com/2014/05/08/nyregion/national-assessment-of-educational-progress-results-in-Connecticut-and-New-Jersey.html

Include the full date in the format Year, Month Day. Do not include a retrieval date for periodical sources found on websites. Note that for citations, include only the year: Baker (2014). For newspaper articles retrieved from a common academic research database, leave out the URL. For newspaper articles from an online news website that is not an online version of a print newspaper, follow the format for a webpage reference list entry.

OASIS Resources

Oasis webpage.

OASIS. (n.d.). Common reference list examples . Walden University. https://academicguides.waldenu.edu/writingcenter/apa/references/examples

For all OASIS content, list OASIS as the author. Because OASIS webpages do not include publication dates, use “n.d.” for the year.

Interactive Guide

OASIS. (n.d.). Embrace iterative research and writing [Interactive guide]. Walden University. https://academics.waldenu.edu/oasis/iterative-research-writing-web

For OASIS multimedia resources, such as interactive guides, include a description of the resource in brackets after the title.

Online Video/Webcast

Walden University. (2013). An overview of learning [Video]. Walden University Canvas. https://waldenu.instructure.com

Use this format for online videos such as Walden videos in classrooms. Most of our classroom videos are produced by Walden University, which will be listed as the author in your reference and citation. Note: Some examples of audiovisual materials in the APA manual show the word “Producer” in parentheses after the producer/author area. In consultation with the editors of the APA manual, we have determined that parenthetical is not necessary for the videos in our courses. The manual itself is unclear on the matter, however, so either approach should be accepted. Note that the speaker in the video does not appear in the reference list entry, but you may want to mention that person in your text. For instance, if you are viewing a video where Tobias Ball is the speaker, you might write the following: Tobias Ball stated that APA guidelines ensure a consistent presentation of information in student papers (Walden University, 2013). For more information on citing the speaker in a video, see our page on Common Citation Errors .

Taylor, R. [taylorphd07]. (2014, February 27). Scales of measurement [Video]. YouTube. https://www.youtube.com/watch?v=PDsMUlexaMY

OASIS. (2020, April 15). One-way ANCOVA: Introduction [Video]. YouTube. https://youtu.be/_XnNDQ5CNW8

For videos from streaming sites, use the person or organization who uploaded the video in the author space to ensure retrievability, whether or not that person is the speaker in the video. A username can be provided in square brackets. As a change from APA 6 to APA 7, include the publisher after the title, and do not use "Retrieved from" before the URL. See APA 7, Section 10.12 for more information and examples.

See also reference list entry formats for TED Talks .

Technical and Research Reports

Edwards, C. (2015). Lighting levels for isolated intersections: Leading to safety improvements (Report No. MnDOT 2015-05). Center for Transportation Studies. http://www.cts.umn.edu/Publications/ResearchReports/reportdetail.html?id=2402

Technical and research reports by governmental agencies and other research institutions usually follow a different publication process than scholarly, peer-reviewed journals. However, they present original research and are often useful for research papers. Sometimes, researchers refer to these types of reports as gray literature , and white papers are a type of this literature. See APA 7, Section 10.4 for more information.

Reference list entires for TED Talks follow the usual guidelines for multimedia content found online. There are two common places to find TED talks online, with slightly different reference list entry formats for each.

TED Talk on the TED website

If you find the TED Talk on the TED website, follow the format for an online video on an organizational website:

Owusu-Kesse, K. (2020, June). 5 needs that any COVID-19 response should meet [Video]. TED Conferences. https://www.ted.com/talks/kwame_owusu_kesse_5_needs_that_any_covid_19_response_should_meet

The speaker is the author in the reference list entry if the video is posted on the TED website. For citations, use the speaker's surname.

TED Talk on YouTube

If you find the TED Talk on YouTube or another streaming video website, follow the usual format for streaming video sites:

TED. (2021, February 5). The shadow pandemic of domestic violence during COVID-19 | Kemi DaSilvalbru [Video]. YouTube. https://www.youtube.com/watch?v=PGdID_ICFII

TED is the author in the reference list entry if the video is posted on YouTube since it is the channel on which the video is posted. For citations, use TED as the author.

Walden University Course Catalog

To include the Walden course catalog in your reference list, use this format:

Walden University. (2020). 2019-2020 Walden University catalog . https://catalog.waldenu.edu/index.php

If you cite from a specific portion of the catalog in your paper, indicate the appropriate section and paragraph number in your text:

...which reflects the commitment to social change expressed in Walden University's mission statement (Walden University, 2020, Vision, Mission, and Goals section, para. 2).

And in the reference list:

Walden University. (2020). Vision, mission, and goals. In 2019-2020 Walden University catalog. https://catalog.waldenu.edu/content.php?catoid=172&navoid=59420&hl=vision&returnto=search

Vartan, S. (2018, January 30). Why vacations matter for your health . CNN. https://www.cnn.com/travel/article/why-vacations-matter/index.html

For webpages on the open web, include the author, date, webpage title, organization/site name, and URL. (There is a slight variation for online versions of print newspapers or magazines. For those sources, follow the models in the previous sections of this page.)

American Federation of Teachers. (n.d.). Community schools . http://www.aft.org/issues/schoolreform/commschools/index.cfm

If there is no specified author, then use the organization’s name as the author. In such a case, there is no need to repeat the organization's name after the title.

In APA 7, active hyperlinks for DOIs and URLs should be used for documents meant for screen reading. Present these hyperlinks in blue and underlined text (the default formatting in Microsoft Word), although plain black text is also acceptable. Be consistent in your formatting choice for DOIs and URLs throughout your reference list.

A reference book is often defined as "a book designed by the arrangement and treatment of its subject matter to be consulted for definite items of information rather than to be read consecutively," and a reference collection as a "collection of reference books and other materials in a library, useful for supplying authoritative information or identifying sources, kept together for convenience in providing information service, and generally not allowed to circulate." ( ALA Glossary… 1998 )

This page contains definitions of and examples of different types of reference sources including:.

Almanacs and Yearbooks

Bibliographies, biographies, chronologies and timelines, dictionaries and thesauri, directories, encyclopedias, handbooks and manuals.

<< Previous: INF 6120 Course Guide
Next: Indexes and Abstracts: A Closer Look >>

Almanacs are usually published annually. Though they are not usually used for extensive research, they contain specific facts, statistics, tables and lists about people, places, events, countries, organizations, zip codes, and popular culture such as sports and entertainment. Generally, almanacs cover a broad period of time. Yearbooks contain similar information, but cover just a given year.

Examples include:.

Atlases contain an organized group of pictorial or illustrated political, cultural, physical, road, and/or thematic maps. Atlases may be organized around a specific subject, theme, or geographic area.

Specialty Map Resource:

Directories contain an organized list of people and/or organizations, and help one to find information such as addresses, phone numbers, and email addresses, etc. for the organizations or people included within the scope of that directory.

Indexes are compilations on information, generally arranged either alphabetically or numerically, that indicate the location of related information either within or outside of the same resource.

Learn more about Indexes and Abstracts.

Chronologies and timelines summarize the advancement of an event or happening by supplying brief milestones in the progression of the event. the summaries will be presented day-by-day, year-by-year, or by another chronological breakdown. .

A gazetteer is a geographical dictionary that includes brief descriptive, geographical, historical, and/or statistical information on specific places. Occasionally, a gazetteer may focus on a specific subject area.

Standard dictionaries give an alphabetical list of words and their definitions, but there are several useful variations also classified as dictionaries. Thesauri contain synonyms and antonyms (opposites) but usually don't define the words. There are also dialect and slang dictionaries, dictionaries of abbreviations and acronyms, dictionaries of quotations, and picture dictionaries. Dictionaries can be unabridged (general) or can be thematically organized in some way.

Encyclopedias contain full coverage of information about an area of knowledge. They can be general or can cover a specific subject, and contain alphabetically organized entries with varying detail. These are great starting points for fact-finding, getting background topic information, learning of key events and individuals, or starting a research project.

Bibliographies compile comprehensive lists of resources that share one or more common attributes about a particular subject, person, geographical area, etc. Some bibliographies also briefly describe the resources that are listed. One should consult a bibliography when they want citations that will guide them to specific resources.

Biographies contain information about people, both living and deceased - they can contain brief summaries of data about individuals, contain lists of citations of resources about a person, or be full length books detailing the life of one particular person. Biographies may cover general important figures, or may be organized thematically/geographically, etc. One would use a biography to look up facts or detailed information about a person or group of people.

A handbook contains facts about a specific subject or instructions that can be used to accomplish something. A handbook can come in several forms, such as a manual for completing tasks, or a guidebook providing information about a subject, region, etc. (such as a travel guidebook). Handbooks are often designed for quick consultation and easy portability.

Reference Resources

R eference sources generally summarize topics or assists in finding secondary literature. These sources provide background information or help you to find other sources. They are also great for quick facts, statistics, or contact information, and can be useful for learning specific vocabulary. Many contain bibliographies for further reading or additional sources on your topic. They are a great starting point for your research.

Most print reference sources cannot be checked out from the library. However, online reference sources are available on the library's website and can be accessed from home, with your SSU Navigator (current students) or Polaris (faculty/staff) username and password.

The print Reference Collection is shelved on the first floor facing the Library Help Desk as you enter the library. Online reference collection is available through library databases.

Encyclopedias

Use to get an overview of a topic or background information, to identify concepts, people and keywords, and to find references for further reading. General encyclopedias are well known, but we also have many subject specific encyclopedias which should not be overlooked. Examples include Encyclopedia of Early Childhood Education , International Encyclopedia of Human Geography , and Encyclopedia of Nursing Education . Online resources: Britannica Library (Encyclopedia) and Funk & Wagnalls of New World Encyclopedia.

Guides and Bibliographies

These provide lists of materials (books, journal articles, etc.) on a subject. Use them to identify references for your research. Bibliographies provide literature on a subject specific or by a specific author. Print Nursing 2019 Drug Handbook. Online resource: Oxford Bibliographies

Dictionaries

Works containing brief explanatory entries for terms and topics related to a specific subject or field of inquiry, usually arranged alphabetically. Entries are usually shorter than those found in encyclopedias.

An alphabetical listing of words in a language with their definitions, pronunciation, etymology, and syllabication. Online examples: New Oxford Rhyming Dictionary, Merriam-Webster Dictionary , Cambridge Dictionaries Online , Visual Thesaurus , and Oxford English Dictionary (Links to an external site.) and, Links to an external sitand

Over the past 70 years, the semiconductor industry has undergone transformative changes, largely driven by the miniaturization of devices and the integration of innovative structures and materials. Two-dimensional (2D) materials like transition metal dichalcogenides (TMDs) and graphene are pivotal in overcoming the limitations of silicon-based technologies, offering innovative approaches in transistor design and functionality, enabling atomic-thin channel transistors and monolithic 3D integration. We review the important progress in the application of 2D materials in future information technology, focusing in particular on microelectronics and optoelectronics. We comprehensively summarize the key advancements across material production, characterization metrology, electronic devices, optoelectronic devices, and heterogeneous integration on silicon. A strategic roadmap and key challenges for the transition of 2D materials from basic research to industrial development are outlined. To facilitate such a transition, key technologies and tools dedicated to 2D materials must be developed to meet industrial standards, and the employment of AI in material growth, characterizations, and circuit design will be essential. It is time for academia to actively engage with industry to drive the next 10 years of 2D material research.

Perovskite solar cells (PSCs) have gained much attention in recent years because of their improved energy conversion efficiency, simple fabrication process, low processing temperature, flexibility, light weight, and low cost of constituent materials when compared with their counterpart silicon based solar cells. Besides, stability and toxicity of PSCs and low power conversion efficiency have been an obstacle towards commercialization of PSCs which has attracted intense research attention. In this research paper, a Glass/Cu 2 O/CH 3 NH 3 SnI 3 /ZnO/Al inverted device structure which is made of cheap inorganic materials, n-type transparent conducting oxide (TCO)-free, stable, photoexcited toxic-free perovskite have been carefully designed, simulated and optimized using a one-dimensional solar cell capacitance simulator (SCAPS-1D) software. The effects of layers’ thickness, perovskite’s doping concentration and back contact electrodes have been investigated, and the optimized structure produced an open circuit voltage (V oc ) of 1.0867 V, short circuit current density (J SC ) of 33.4942 mA/cm 2 , fill factor (FF) of 82.88% and power conversion efficiency (PCE) of 30.17%. This paper presents a model that is first of its kind where the highest PCE performance and eco-friendly n-type TCO-free inverted CH 3 NH 3 SnI 3 based perovskite solar cell is achieved using all-inorganic transport materials.

Introduction.

Due to the enormous energy demand brought on by the growing world population, energy consumption is increasing at fast rate every day. Fossil fuels provide about 80% of the world’s energy requirements 1 , which have negative environmental effects and have forced the development of renewable energy sources 2 . Because of its abundant, clean, and limitless nature, solar energy is regarded as the most major and significant source of renewable energy 3 , making it the most promising contender because of its affordability and sustainability 4 . The generations of solar cells is recently categorized into four; the crystalline silicon (c-Si) and gallium arsenide (GaAs) constitute the first generation, while the thin films such as copper indium gallium selenide (CIGS), amorphous silicon (a-Si) and cadmium telluride (CdTe), formed the second generation. The evolving class of solar cells such as dye-sensitized solar cells (DSSC), copper zinc tin sulfide (CZTS) and quantum dot (QD) belongs to the third generation while the novel solar cells recognized as “inorganics-in-organics” such as hybrid perovskites represents one of the candidates of fourth-generation solar cells 5 . The monocrystalline and polycrystalline silicon-based are the known two kinds of solar cells 6 . Solar cells based on CdTe 7 , 8 , quantum dot sensitized-based solar cells 9 , CIGS 10 , 11 , organic photo cells 12 and perovskite-based solar cells 13 have also been explored by researchers.

The metal halide perovskites are represented by ABX 3 , where A refers to an organic cation, B refers to a metal cation, and X refers to a halogen anion. The cation embraces individual or mixed compositions of methylammonium (MA), cesium (Cs), and formamidinium (FA), whereas the halogen anion embraces individual or mixed compositions of Cl, Br, and I 14 . Recent researches have focused on perovskite solar cells (PSCs), due to their increased efficiencies 15 , low processing temperatures, high absorption, long diffusion length, high charge mobility, low trap density, low exciton binding energy, tunable bandgap and low-cost of fabrication 14 , 15 . PSCs have been the subject of numerous studies, which have improved energy power conversion efficiencies (PCEs) from 3.8% in 2009 to about 25% after 13 years of development 16 , while 15 reported PCE of 25.6%, and 26.1% have recently been attained 17 . The impressive characteristics of perovskite materials include good charge carrier mobility, high coefficient of absorption, high diffusion charge carrier and low binding energy 18 , 19 . Because of their excellent photovoltaic performance, methyl ammonium lead halides, both pure and modified, have been the subject of several studies 20 , 21 . However, lead-based electronics posed hindrance to commercialization due to its harmful nature 14 , 22 , 23 , 24 . Recent reports revealed stern circumscribe of lead-based electronics devices by many countries, notably the European Union because of its toxic nature to human and environment irrespective of their high-power conversion efficiency 25 , 26 , 27 , 28 .

Some of the major challenges affecting the large-scale production of PSCs is the high cost of electron and hole transport materials, toxicity of the perovskite materials and degradability of the solar cells. Despite significant improvements made thus far, high temperature and humidity as well as the presence of moisture results to reduced lifespan of some perovskite materials such as Spiro-OMeTAD, the popular hole transport material. The difficulty in processing, and the expensive nature of Spiro-OMeTAD is a possible impediment to commercialization of PSCs going forward 29 , 30 , 31 , 32 . Additionally, the Spiro-OMeTAD layer aids polarisation of the electrode and plays a significant part in the current density–voltage (J–V) hysteresis phenomenon, which ultimately influence the device’s instability 33 . Conventional structures of PSCs using organic-based materials as hole transport medium and the metallic electrodes constitute the major reasons for the PSCs’ shorter life span 34 . Pin-holes in the HTM have been a challenge of interest in recent studies as it leads to poor PSC’s stability owing to penetration of oxygen and ambient moisture which deteriorates the perovskite absorbent layer. Numerous attempts have been made to address the detrimental effects of pinholes in HTMs and perovskites. One of such efforts is the significant improvement of stability in perovskite solar cells through the use of doping engineering to create a hole transport layer free of pinholes 35 . Investigations by other scientists have concentrated on creating effective PSCs employing novel kinds of hole-transport materials as replacement to Spiro-OMeTAD 36 , 37 , or PSCs without HTL that are suitable for streamlining the device’s ideal process, and further reduce manufacturing cost and as well prevents perovskite’s degradation 38 , 39 , 40 . There is no doubt that the absence of pinholes in HTM layer considerably increases the PSC’s device stability under operating environments 41 .

Regardless of tremendous research progresses in PCSs, planar inverted PSCs have received lesser interest, hence limited research work is conducted in this area of study despites their easy fabrication, cost-effectiveness, and suppressed hysteresis characteristics 42 . Therefore, intense study is required in this field of study to improve and maximize their performances as compared to their conventional counterparts’ structures. Most of the available researches on inverted planar PSCs have focused on the use of gold as contact electrode, spiro-OMeTAD as HTM with a maximum achievable PCE of approximately 30% through simulations 43 , 44 , 45 , 46 , 47 .

This research sought to streamline production innovations in PSCs, lower production costs, and maximise performance. The use of eco-friendly perovskite material, cheap and suitable all-inorganic transport materials and the use of the appropriate back contact electrode will increase efficiency, stability, and significantly reduce the production costs. The possibility of attaining high efficiency by utilising the inverted planar technique without using silicon composites and organic HTMs can lead to a greater variety of benefits in the sector. This paper presents a simulation of an inverted planar and n-type transparent conducting oxide-free structure using inorganic transport materials. The selection of appropriate back contact electrode, variation of system’s parameters such as thickness of HTM, absorber material, ETM, absorber doping concentration and determination of optimal values of series and shunt resistances is carried out to achieve optimal performance of the device.

Materials and methods

Device structure and simulation.

There are different types of software used for simulation of solar cells such as PC1D, ASA, Amps-1D, WxAMPS, SCAPS-1D, SETFOS, Gpvdm, AFORS-het, Aspin-2D, PECSIM, Adept, TCAD, Atlas, Silvaco etc. However, SCAPS-1D software is used in this work to simulate an inverted tin-based perovskite solar cell with planar heterojunction because of its best accurate non-commercial tool that is straightforward in operation, with friendly dialog box and extremely quick in simulations at no additional expense and support for multi-junction solar cells 48 . Three related differential equations were solved to determine the energy bands, quantum efficiency of the device, current density–voltage (J–V) curve, and recombination rate curve. The Poisson Eq. ( 1 ), the electron continuity Eq. ( 2 ), and the hole Eq. ( 3 ) are built in the SCAPS-1D software. These curves are used to compute the solar cell device’s open circuit voltage (V oc ), short circuit current density (J SC ), fill factor (FF), and power conversion efficiency (PCE).

where $G$ , ${\tau }_{n}$ , ${\tau }_{p},$ $D$ , $q$ , $\varepsilon$ $\psi,$ ${\mu }_{n}$ , ${\mu }_{p}$ , $n\left(x\right), p\left(x\right),$ ${n}_{t}(x)$ , ${p}_{t}\left(x\right),$ ${N}_{A}^{-}(x),$ ${N}_{D}^{+}\left(x\right)$ and $E$ represent the rate of generation, life time of electron, life time of hole, diffusion coefficient, electron charge, permittivity, electrostatic potential, electron mobility, hole mobility, concentration of free electrons, concentration of free holes, concentration of trapped electrons, concentration of trapped holes, ionized acceptor concentrations, ionized donor concentrations, and electric field respectively. Meanwhile, x represents the direction along the thickness of the solar cell 49 .

The device’s structure is composed of Cu 2 O as HTM layer, CH 3 NH 3 SnI 3 as absorber layer and ZnO as ETM layer. The choice of Cu 2 O as HTM in this work over other HTMs is based on the fact that it is relatively cheap when compared to organic based HTMs, high absorption coefficient, high intrinsic hole mobility, and acceptable energy levels that are aligned with the absorber layer (MASnI 3 ), high photochemical and thermal stability as well as long-term stability in air 50 . Similarly, CH 3 NH 3 SnI 3 is also adopted as the absorber layer because of its eco-friendliness with potentials for commercialization 51 , 52 and superior optoelectronic properties with 1.3 eV direct band gap, which is an appropriate range for the absorber layer 21 , 49 , 53 , 54 . Meanwhile, ZnO is used as ETM because of its high absorption coefficient, higher electron mobility 2 , 51 and aligned energy bandgap with the chosen perovskite (MASnI 3 ) when compared to the SnO 2 36 .

Background and selection of device parameters

Light generates electron–hole pairs within the absorber layer. The junction field draws holes to the HTM layers and electrons to the ETM layers, respectively. The thickness, coefficient of absorption, and mobility of the active material all affect the device’s J SC . The photocurrent will increase as the absorption coefficient increases 49 , 54 , 55 . Another important consideration is the absorber’s thickness, which must be sufficient to absorb the maximum cutoff wavelength of the incident solar light 49 , 53 . Aside from that, mobility is essential to achieving the high J SC which is ideally equal to the current in the solar cell. For the sample of CH 3 NH 3 SnI 3 produced using the open tube approach, a very high mobility of electrons (2000 cm 2 /Vs) and holes (300 cm 2 /Vs) was discovered by Ma et al. and Stoumpos et al. 56 , 57 . Lazemi et al. reported a high value of J SC using similar values of carrier mobility 53 . Devi et al. 58 and Khattak et al. 59 have taken into account the equal and noticeably lesser values of the electron and hole mobility, which are 1.6 cm 2 /Vs and 0.16 cm 2 /Vs respectively. In line with experimental work done by 60 , the electron (2000 cm 2 /Vs) and hole (300 cm 2 /Vs) mobility values for CH 3 NH 3 SnI 3 is adopted for use in this study. It is important to note that diffusion length also has a proportionality relationship to the square root of mobility 58 .

The device simulation was conducted under the 1000 W/m 2 light illumination at 300 K temperature and 1.5G air mass. The proposed device’s series resistance was adjusted to 1 Ωcm 2 while the shunt resistance at 10 4 Ωcm 2 during simulation. The value of work function for front electrode (Cu 2 O) is 5.0 eV while the surface recombination velocity for electrons and holes as 10 5 cm/s and 10 7 cm/s respectively. Moreover, the work function for the back contact electrode ticked as flat band with surface recombination velocity for electrons and holes as 10 7 cm/s and 10 5 cm/s respectively at the beginning of the simulation until an optimized back contact electrode work function was determined as discussed in section " Effect of back contact electrode on the proposed inverted perovskite solar cell ". The characteristics of the device’s material parameters adopted were carefully selected from theories, experiments and research reviews is presented in Table 1 , while the interface parameters are presented in Table 2 . Scientifically, the neutral defect type adopted in the simulation means non-reactive, which can further be explained as a situation where there is no donor nor acceptor of charges within the films of a layer or interface. The bulk defect densities of the materials were chosen above ideal values to demonstrate ideal experimental conditions.

Various decisive parameters like electron mobility, hole mobility, carrier diffusion length, interfacial resistance, etc., have been considered constant and taken from the literature. These parameters are extremely dependent on experimental processes and can hugely alter practical performance of the device. The relative humidity, temperature, the type of instruments used, procedural and human expertise, control of crystallization and grain growth rates are some of the factors behind the real-life performance and their variations from theoretical values.

Results and discussions

In general, the electron and hole pairs are produced within the absorber layer after illumination. The junction field causes holes and electrons to travel in the directions of HTM and ETM layers, respectively. A voltage is created when these holes and electrons are collected at the anode and cathode, respectively. The simulation results of the proposed inverted device structure Cu 2 O/CH 3 NH 3 SnI 3 /ZnO using the available initial device parameters as contained in Tables 1 and 2 shows the J–V characteristics of the proposed device as shown in Fig. 1 produced a Voc of 0.9854 V, J SC of 30.4185 mA/cm 2 , an FF of 82.48% and PCE of 24.72%. The proposed device structure Cu 2 O/MASnI 3 /ZnO underwent further simulation and optimization so as to obtain optimized thickness of the constituent layers.

Effect of back contact electrode on the proposed inverted perovskite solar cell

Various metal back contact electrodes such as aluminium (4.26 eV), tin (4.42 eV) graphene (4.60 eV), silver (4.74 eV), iron (4.81 eV) and copper (5.00 eV) have been tested on the proposed inverted structure so as to determine the most appropriate one to be used for enhanced optimal performance. Figure 1 shows the work function of various metals used as back contact electrodes and their associated photovoltaic parameters on the proposed IPSC based device simulated using initial given parameters presented in Tables 1 and 2 . The results in Fig. 1 clearly show that the choice of aluminum (Al) for back electrode maintained the most optimal device performance, as the V oc , J SC , FF and PCE of 0.9854 V, 30.4185 mA/cm 2 , 82.48% and 24.72% respectively is produced. It is interesting to note in this model that the J SC (Fig. 1 b) remains constant as the work function of the back contact varies while the V OC , FF and PCE declines as the work function increases from 4.26 to 5.00 eV (Fig. 1 a,c,d). For p–n configuration, the current is negative because of the uphill diffusion of the minority charge carriers in terms of concentration gradient arising from reverse bias during solar illumination. The current growth from the negative quadrant towards the positive quadrant signifies power generation up to zero value of current where an open circuit voltage (V OC ) of 0.9854 V is achieved. The J–V characteristics of the device having used aluminum as the back contact electrode is shown as Fig. 2 .

There is no experimental result for this exact structure (Cu 2 O/CH 3 NH 3 SnI 3 /ZnO/Al) known to us, which makes this research novel and interesting. There is no clear reasons why the lack of experimental works to support this study, but this could be due to lack of good conductivity of all-inorganic transport materials in nano electronics compared to organic transport materials and high processing temperature required. However, there are few simulation results of exact combination in n–i–p structure reported in 63 , 64 . The PCEs of 26.55% and 9.27% respectively were obtained in 63 and 64 , while our designed n-type TCO-free p-i-n device produced a superior PCE of 30.17% as shown in Fig. 8 .

The proposed inverted model will not simulate when the conventional n-type TCO (ITO/FTO) of donor concentration ND is used with the acceptor concentration NA being zero, except an organic p-type TCO is used which is outside the scope of this study. It’s worth noting that the top transparent glass used as presented in Fig. 16 is an n-type TCO-free substrate in order to avoid non-convergence of voltage between the front and back electrodes when a conventional n-type TCOs are used. The carefully chosen transparent glass substrate size of 50 nm is not included in the simulation model, hence it is undoped and may not have significant impact on the device in real experimental situation. In this work, it is difficult to drive an output from the device if a TCO of an n-type material (FTO/ITO) is used as front electrode in the inverted structure when the same n-type material of same polarity is used as back hole blocker (ZnO) because of non-voltage convergence arising from non-compatible work function between the layers. The non-voltage convergence experienced when ITO with metal function of 4.7 eV is used is as a result of non-ideal band gap between the adjacent semiconductors layers (ITO/Cu 2 O) which makes the proposed n-type TCO-free model feasible. However, a back contact electrode of low metal function lower than ZnO like aluminium (4.26 eV) is required for optimal performance.

The use of Cu 2 O as front contact electrode may suffer setback due its high sheet resistance and poor conductivity when compared to n-type TCOs. However, the sheet resistance of most metal oxides depends on the method of deposition, temperature, oxygen flow rate and thickness of the films. The control of power and oxygen flow rates during deposition of copper oxide thin films at a thickness of less than 100 nm prepared by reactive magnetron sputtering can reduce the sheet resistance and enhance performance of the device in practical sense 65 . The provision of a high density of low energy sputtered copper radicals/ions, and when combined with a controlled amount of oxygen, can produce good quality p-type transparent Cu 2 O films with electrical resistivity ranging from 10 2 to 10 4 Ω-cm 66 which makes Cu 2 O a potential transparent front conducting oxide for photovoltaic applications. Also, the doping of Cu 2 O with nickel can improve its p–type conductivity via extrinsic doping and post–growth processing 67 . Therefore, the Cu 2 O may not be as conductive as other n-type TCOs in experimental sense but runs conveniently in the simulation model without challenge which means the proposed n-type TCO–free model is novel and less complex, providing good direction in the design and modeling of simple inverted perovskite solar cells as shown in Figs. 13 and 16 . Cu 2 O can act as a front electrode efficiently provided its thickness is thin enough to ensure adequate clarity and transparency to enhance admittance of photons into the absorber (perovskite) layer.

Effect of thickness of the HTM (Cu 2 O), absorber (CH 3 NH 3 SnI 3 ) and ETM (ZnO) layers

In this study, the variation of HTM’s layer thickness from 10 to 100 nm results to a slight increase in FF (Fig. 3 c) while a decline in device parameters such as V OC , J SC and PCE is experienced as presented in Fig. 3 a,b,d respectively.

The thickness of the absorber layer considerably affects the solar cell’s overall performance. The increase in absorber’s thickness decreases the V OC due to increase in series resistance. Meanwhile, the increase in absorber’s thickness increases the J SC, FF and PCE to the maximum after which it decreases with further increase in thickness. In this study, the thickness of CH 3 NH 3 SnI 3 has been adjusted in this simulation from 100 to 1500 nm. The fluctuation of photovoltaic characteristics with thickness of absorber layer is shown in Fig. 4 . The V OC declines as a result of faster recombination due to increased thickness (Fig. 4 a). A thicker absorber layer absorbs more photons, which increases short circuit current density (J CS ) and the fill factor (FF) and as seen in Fig. 4 b,c, respectively. The solar cell efficiency is increased as the thickness of absorber layer increases up to an ideal thickness for the solar cell after which efficiency declines (Fig. 4 d). However, as diffusion necessitates a longer charge travel distance, recombination is more common in larger absorber layers; hence, efficiency decreases after a certain thickness value. Our results concur with experimental findings in 62 , 68 . As shown in Fig. 4 d, the ideal absorber layer thickness for this inverted PSC is achieved between 1200 and 1300 nm.

Nevertheless, the increase in ETM’s thickness leads to a non-noticeable change in V OC , J SC , FF and PCE (Fig. 5 a–d) respectively. Therefore, it can be inferred that while device performance is mostly determined by absorber thickness, IPSC device performance is not influenced by the ETM layer’s thickness but rather varies slightly with the HTM’s thickness, which is designed to be small enough to guarantee optical transparency and ensure easy photon penetration to the absorber layer. The selection of optimal thickness is important to regulate series and shunt resistance and ensure improved device performance in terms of short circuit current, open circuit voltage, fill factor and power conversion efficiency.

Simulation and thickness optimization of the proposed device structure

Simulation and optimization of the proposed device shows that the HTM (Cu 2 O) layer, the absorber (MASnI 3 ) layer and ETM layer (ZnO) have been optimized to the thickness of 40 nm, 1200 nm and 200 nm respectively. The simulation of these optimized dimensions led to an improvement in the solar cell parameters as it produced a Voc of 0.9633 V, J SC of 33.8049 mA/cm 2 , FF of 82.84% and PCE of 26.97% as shown in the J–V characteristics curve (Fig. 6 ).

Effect of absorber’s doping concentration (NA)

The holes’ acceptor density of the absorber layer has a major impact on the photovoltaic cell’s device performance in addition to its thickness. As demonstrated in Fig. 7 , the Fermi energy level of the hole falls with increasing doping concentration of the acceptor, and as a result, V OC increases (Fig. 7 a). Also, an increase in the doping concentration of the acceptor leads to a built-in potential that increases charge separation, which in turn causes a rise in V OC . In this work, the acceptor concentration NA (1/cm 3 ) of the absorber layer is varied within a range of 3 × 10 14 cm −3 to 3 × 10 21 cm −3 to ascertain the most optimal value that can produce an optimal performance of the proposed device. Nevertheless, J SC maintains a steady decline marginally up to NA’s value of 3 × 10 19 cm −3 before falling off sharply. At the same NA’s value, the value of FF drops suddenly which might be caused by a rise in the rate at which charge carriers within the absorber layer recombine or an increase in series resistance 55 . The absorber layer’s doping concentration value of 3 × 10 19 cm −3 produced the best cell performance having V oc of 1.0867 V, J SC of 33.4942 mA/cm 2 , FF of 82.88% and PCE of 30.17% as shown in Fig. 7 a–d respectively, while its J–V characteristics is shown as Fig. 8 .

The complex nature of an organic molecule in the A site of the perovskite structure (ABX 3 ) may be the cause of degradation, as evidenced by the absorber’s bandgap of 1.3 eV and the measured Voc of 1.0867 V. Using varying ratios of the precursors causes an intrinsic fault when the perovskite structure is distorted. Higher degrees of crystallization and a slower rate of breakdown are the results of vacancies in the structure caused by the excess CH 3 NH 3 I (MAI). The crystalline lattice’s anomalies emphasize the role MAI plays in the deterioration process. Excess MAI may potentially release halide ions, depending on the concentration. Afterwards, these halide ions function as dopants, altering the perovskite semiconductors' bandgap 69 . When exposed to air, the Sn 2+ in CH 3 NH 3 SnI 3 is changed to Sn 4+ (a process known as self-doping), converting the device into a p-type semiconductor. Sadly, this procedure deteriorates the device performance, such as the output power and the power conversion efficiency 56 , 70 .

Effect of series resistance R series and shunt resistance R shunt

The resistance in series and shunt (R series and R shunt ) affects the J–V curve’s form and slope, which in turn affects the solar cell’s efficiency. The connections electrodes, electrical dissipation in the perovskite, and layers of hole and electron transport materials (HTM and ETM) are primarily linked to the cause of the R series . However, different recombination pathways, device design, and defects induced during the layer deposition process are linked to the cause of the R shunt . According to the literature, a high shunt resistance and a low series resistance are necessary for a solar cell to have a high efficiency. Electrons cannot flow freely across a circuit if the series resistance is large, and leakage current will occur if the shunt resistance is low, producing PSCs with low stability and efficiency. When there’s a low shunt resistance or a high series resistance, the PSC’s maximum output and FF would both drop 71 , 72 . The ideal diode model’s Eq. ( 4 ) was applied in order to comprehend the impact of R series and R shunt on the perovskite solar cell’s performance 73 .

When $J\approx$ 0 mA/cm 2 for open circuit state, the variables V OC and R shunt relationship is presented in Eq. ( 5 )

where J is the current flowing via the external circuit, V is the output voltage, A is the ideality factor, k is the Boltzmann constant, T is the temperature, q is the electron charge, J O is the saturation current density and J L is the light-induced current density. As a result, low R shunt reduces photovoltaic voltage and may also have an impact on the photocurrent that is collected, whereas high R series values primarily influence the FF and Jsc values 72 .

While keeping the other simulation parameters same, R series and R shunt were changed from 0 to 100 Ωcm 2 and 10 3 Ωcm 2 to 10 10 Ωcm 2 respectively, to better understand their influence on the J–V curves. The responses of V OC , J SC FF and PCE as a function of R series are presented in Fig. 9 . V OC stays fairly constant, J SC falls from 33.51 to 10.77 mA/cm 2 , and FF drops from 85.63 to 24.88% while R series grows from 0 to 100 Ωcm 2 . As a result, as Fig. 9 d illustrates, PCE’s behavior is precisely proportional to J SC and FF, decreasing from 31.16 to 2.91% for the same range. Alternatively, as Fig. 10 illustrates, when R shunt rises from 10 3 to 10 10 Ωcm 2 , V OC rises from 1.0858 to 1.0868 V, J SC maintains a constant 33.49 mA/cm 2 from 10 4 Ωcm 2 , FF rises from 80.75 to 83.12%, and the PCE rises from 29.34 to 30.26% respectively (Fig. 10 a–d). For R series and R shunt , the optimal values are therefore 1 Ωcm 2 and 10 6 Ωcm 2 respectively, which is in conformity with literature.

Effect of the defect state of bulk and interface layers

The impact of the absorber’s defect density is an important factor that needs to be examined. In the absorber layer, defects are inevitable. Both at surfaces and in the bulk, they are present. Point defects in the perovskite absorber layer include lattice vacancies, interstitial, Schottky, and Frenkel defects. In addition, there may be higher order defects like grain boundaries and dislocations 74 . The self-doping process in the absorber layer creates the p-type semiconductor that results in an impurity defect 54 , 56 , 75 , 76 . These defects cause the energy bandgap to appear at shallow or deep levels 74 . Charge carriers have the ability to capture and promote nonradiative recombination of electron–hole as a result of these defects 53 , 55 . Noteworthy, the simulated interface defect density for both electron and hole recombination velocities was 1 × 10 -2 cm/s for both HTM/MASnI 3 and ETM/MASnI 3 interface. In the Sn-based perovskite absorber layer, the electron and hole diffusion lengths were 16 µm and 6.2 µm, respectively. The optimized device’s absorber defect density (Nt) of 2 × 10 15 cm −3 achieved a V OC of 1.0867 V, a J SC of 33.4942 mA/cm 2 , FF of 82.88%, and a PCE of 30.17%. Nevertheless, synthesizing a material with a low defect density value is a challenging task in an experiment 55 .

The Shockley–Read–Hall (SRH) recombination model has been applied to provide understanding regarding the impact of defect density in the absorber layer on device performance 49 , 53 , 77 . The effect of defect density on the recombination rate based on the SRH recombination model is essential to determining the critical influence of Nt on the device performance. The plot of recombination rate with depth from the optimized device’s surface is depicted in Fig. 11 .

Recombination rate of the optimized device with depth from the surface.

The proposed device produced quantum efficiency curve covering the entire visible spectrum (300–900 nm) achieving an optimum quantum efficiency (QE) of 99.38% at 580 nm wavelength, which is in agreement with other works 15 , 43 , 54 , 61 , 78 , 79 is presented as Fig. 12 . The simulated inverted structure, energy band diagram, energy band alignment and complete device structure of the optimized inverted planar perovskite solar cells are presented as Figs. 13 , 14 , 15 and 16 , respectively. It’s very clear that the photovoltaic performance of the proposed device as shown in Table 3 is superior to other related works reported in the literature.

The toxic-free CH 3 NH 3 SnI 3 as light harvesting material is explored in this study. A heterojunction planar perovskite solar cell with an inverted structure Glass/Cu 2 O/CH 3 NH 3 SnI 3 /ZnO/Al was simulated, optimized and analyzed in this paper. In relation to various photovoltaic parameters such as the work function of the back contact electrodes, thickness of the HTM layer, absorber and the ETM layers, and the absorber’s doping concentration were optimized. The thickness of the HTM, absorber layer and ETM were optimized to 40 nm, 1200 nm and 200 nm respectively. The optimized structure produced an enhanced Voc of 1.0867 V, J SC of 33.4942 mA/cm 2 , FF of 82.88% and PCE of 30.17% respectively. The results indicate that an increase in doping concentration of the absorber increased the Voc, FF and PCE but decreased the J SC of the solar cell. The interface between the ETM/back-electrode requires a cheap and low work function metal for enhanced performance. The n-type TCO-free inverted CH 3 NH 3 SnI 3 -based PSC provides a potential path to attaining simple, eco-friendly, cheap and highly efficient perovskite solar cell device using all-inorganic transport materials.

Metrics details

The etonogestrel contraceptive implant is currently approved by the United States Food and Drug Administration (FDA) for the prevention of pregnancy up to 3 years. However, studies that suggest efficacy up to 5 years. There is little information on the prevalence of extended use and the factors that influence clinicians in offering extended use. We investigated clinician perspectives on the barriers and facilitators to offering extended use of the contraceptive implant.

Using the Consolidated Framework for Implementation Research (CFIR), we conducted semi-structured qualitative interviews. Participants were recruited from a nationwide survey study of reproductive health clinicians on their knowledge and perspective of extended use of the contraceptive implant. To optimize the diversity of perspectives, we purposefully sampled participants from this study. We used content analysis and consensual qualitative research methods to inform our coding and data analysis. Themes arose deductively and inductively.

We interviewed 20 clinicians including advance practice clinicians, family medicine physicians, obstetrician/gynecologist and complex family planning sub-specialists. Themes regarding barriers and facilitators to extended use of the contraceptive implant emerged. Barriers included the FDA approval for 3 years and clinician concern about liability in the context of off-label use of the contraceptive implant. Educational materials and a champion of extended use were facilitators.

Conclusions

There is opportunity to expand access to extended use of the contraceptive implant by developing educational materials for clinicians and patients, identifying a champion of extended use, and providing information on extended use prior to replacement appointments at 3 years.

Peer Review reports

The etonogestrel contraceptive implant is currently approved by the U.S. Food and Drug Administration (FDA) for 3 years of continuous use for the prevention of pregnancy [ 1 ]. However, there is evidence to support its use for up to 5 years while maintaining a low risk of pregnancy [ 2 , 3 , 4 ]. The off-label use of the contraceptive implant past its FDA-approved duration and up to 5 years is known as extended use. Importantly, the FDA supports off-label use of marketed drugs and medical devices so long as there is strong relevant published evidence [ 5 ]. Off-label use such as extended use of the contraceptive implant is common with many other reproductive devices and medications, including misoprostol for labor induction, the copper intrauterine device (IUD) for emergency contraception, and, prior to its recent FDA-approval for extended use, the 52 mg levonorgestrel (LNG) IUD for pregnancy prevention. The 52 mg LNG IUD was previously FDA-approved for 5 years, however strong published evidence demonstrated longer efficacy up to 8 years, leading clinicians to counsel on extended use and eventually contributing to updated federal guidelines [ 6 , 7 ].

Though there are clinicians who counsel patients on extended use of the contraceptive implant, many patients still undergo implant replacement after only 3 years of use [ 8 , 9 ]. Continuation rates of the contraceptive implant after 1 and 2 years of use is estimated to be at 81.7% and 68.7%, with the most common reason for early discontinuation prior to 3 years being changes to bleeding pattern [ 10 , 11 , 12 , 13 ]. Ali et al. report the most common reasons that patients decided to stop implant use in years 4 and 5: unspecified personal reasons, desired fertility, bleeding problems, and other medical reasons [ 4 ]. Additionally, a recent nationwide, web-based survey amongst a diverse group of reproductive health clinicians investigated the barriers and facilitators regarding extended use of the contraceptive implant up to 5 years [ 14 ]. The most common barriers found in the study were provider concerns about pregnancy risk and the current FDA approval for only 3 years of use. The key facilitators included strong published evidence supporting extended use and patient and clinician education on extended use. Other than these studies, the patient and clinician factors that facilitate and hinder widespread implementation of extended use of the contraceptive implant have not been explored.

Increasing implementation of extended use of the contraceptive implant across practice settings may decrease unnecessary procedures, devices, healthcare visits, and could improve access to, and satisfaction with, the contraceptive implant. Long-acting reversible contraceptive (LARC) methods such as the contraceptive implant and LNG IUD have significantly higher continuation and approval rates and are more efficacious at preventing pregnancy than non-LARC methods such as oral contraceptive pills and depot medroxyprogesterone acetate injection [ 12 , 15 , [ 16 ]. Given the continued high rates of unintended pregnancies in the United States and the consequential increase in healthcare costs and poor outcomes secondary to pregnancy complications, efficacious pregnancy prevention is an important public health objective and cost-saving measure [ 17 ].

Using a qualitative approach guided by an implementation science framework, the Consolidated Framework for Implementation Research (CFIR), [ 18 ] we sought to explore clinician perspectives on extended use of the contraceptive implant up to 5 years as well as the perceived barriers and facilitators for clinicians to offer extended use.

We conducted semi-structured interviews with 20 clinicians including obstetrics and gynecology generalists, family medicine physicians, complex family planning sub-specialists, and advanced practice clinicians. We recruited interview participants from a nationwide, web-based survey that assessed the prevalence of extended use of the contraceptive implant [ 17 ]. This study recruited respondents through email listservs for the Fellowship in Complex Family Planning, the Ryan Residency Training in Family Planning Program, women’s health nurse practitioners, and family medicine physicians, as well as private social media groups for obstetrician-gynecologists. The total reach of the survey was unknown, however, the study had a survey completion rate of 66.6% ( n = 300/450). Of the 300 completed surveys, 290 respondents indicated their interest in being interviewed (96.7%).

Among the survey respondents, we invited 24 clinicians to participate in interviews, yielding an 83.3% response rate. We selectively recruited interview participants to enrich our sample, specifically focusing on clinician type, practice setting, and region of practice within the United States (U.S.). We also selected interview participants based on whether they always, sometimes, or never counsel on extended use to investigate a broad range of perspectives. For this study, offering extended use is defined as counseling on use past the current FDA-approved duration of 3 years and up to 5 years of use. Offering extended use can occur at any clinical encounter, including insertion appointments, replacement and removal appointments at or before 3 years, and general reproductive health appointments. Clinicians who always offer extended use were defined as those who counsel on extended use to patients who are considering or currently have the contraceptive implant. Clinicians who sometimes offer extended use were defined as those who counsel on extended use, but only to particular patients based on patient-specific factors such as body mass index or insurance coverage. Clinicians who never offer extended use were defined as those who never counsel on use of the contraceptive implant past 3 years of use.

The interview guide was created utilizing an implementation science framework that identifies factors for effectively enacting interventions [ 18 ]. The Consolidated Framework for Implementation Research (CFIR) is organized into 5 major domains: characteristics of the intervention, individual characteristics, inner setting, outer setting, and the process of implementation. The first domain, intervention characteristics, relates to the inherent qualities of the intervention, such as pharmacologic properties and side effects of the contraceptive implant when used up to 5 years. Individual characteristics relates to the roles and characteristics of individual patients and clinicians interacting with the intervention, such as educational background and type of insurance coverage. The inner setting domain assesses the internal setting in which an intervention will be implemented (i.e., clinic type, culture, and policies). The broader context in which an intervention will be implemented, including national policies and social norms is evaluated within the outer setting domain. Finally, the process of implementation domain explores the activities and strategies used to implement the intervention, such as educational materials or clinician and staff trainings on extended use.

We designed the interview guide around these specific domains with questions that aimed to identify targeted strategies to support successful implementation. The complete interview guide is in Appendix A . The interview guide was designed with input from clinicians who regularly prescribe contraception, including extended use of the contraceptive implant, as well as CFIR and implementation science experts. The Human Research Protection Program at our institution approved the study.

A single research team member conducted semi-structured interviews via secure video conference between July and August 2021. Interview participants provided informed consent. All participants were asked a full set of open-ended questions based on the interview guide, with focused follow-up questions to further investigate potential themes or to clarify points. All interviews were audio recorded, then transcribed. For data analysis, we used a content analysis approach to identify concepts and patterns within the dataset [ 19 ]. Themes arose deductively and inductively, with deductive themes identified from the CFIR domains and inductive themes arising from interview insights. Consensual qualitative research methods informed both our data analysis and coding process [ 20 ]. Three authors were involved in the thematic coding of the transcripts. Initially, 5 transcripts were independently coded then checked for inter-coder reliability. Any disagreements were discussed, and a consensus was achieved. The remaining transcripts were then coded by one of the three authors. Once all interviews were coded, major themes and representative quotes were identified. The research team utilized ATLAS.ti for analysis [ 21 ].

Between July and August 2021, we interviewed 20 clinicians from a variety of clinical settings, regions, and women’s health professions, achieving the intended diversity of perspectives (Table 1 ). Among participants, 7 (35.0%) always, 8 (40.0%) sometimes, 5 (25.0%) never offer extended use of the contraceptive implant (Table 2 ).

Characteristics of the intervention

We found that changes to bleeding pattern in or after the third year of use was a barrier to clinicians offering extended use of the contraceptive implant. The participants in this study noted that perceived increases in the irregularity or frequency of a patient’s bleeding makes extended use of the implant difficult for patients to accept. One clinician noticed that some patients correlate changes in their bleeding pattern with a perceived decrease in the efficacy of their implant:

"People who do start noticing changes in bleeding pattern […] [and] associating that with, ‘Oh, my implant is wearing out or becoming expired. I need to get this changed out."

-Complex Family Planning Specialist, Southwest, Academic Setting, sometimes offers extended use

The same clinician discussed that more research on bleeding patterns in the extended use period and potential treatments for implant-associated irregularities could be a facilitator of extended use:

"For bleeding, I think it would be awesome if there is a research study, looking at use of OCPs [oral contraceptive pills] to manage bleeding near the end of the use of an implant or near that three-year mark,, […] So that we could give people… Honestly, either a natural history or a, ‘Here’s how you can manage that if you do want to keep using your implant longer.’"

- Complex Family Planning Specialist, Southwest, Academic Setting, sometimes offers extended use

Information on the bleeding pattern in years 4 and 5 of use and how clinicians can address irregular bleeding during implant use may increase acceptability of extended use.

Individual characteristics

We found that insurance impacts whether a clinician offers extended use:

"I do sometimes have patients saying, ‘I might be changing jobs or I’m going to be turning 27 or whatever.’ And so insurance is a barrier and so they’re like, ‘I want the new one while I still have this insurance.’"

- Family Medicine Physician, Midwest, Community Setting, sometimes offers extended use

Many participants agreed with this concept and stated that acceptability of extended use depends on a patient’s perception of their future insurance status. Clinicians observed that if a patient believes they will have coverage for a replacement or removal in the future, they are more likely to pursue extended use of their implant. Conversely, one clinician discussed how lack of current insurance coverage could be a facilitator of extended use:

"So, I would generally offer extended use to people that didn’t have insurance and would have to self-pay. I would like go through the data with them so they wouldn’t have to pay like $1,000 to get a new implant because it could work another year, or people that were concerned about changing side effects at that time."

- Obstetrician-Gynecologist, Southwest, Academic Setting, sometimes offers extended use

Overall, clinicians perceived that patients’ concerns about current and future insurance coverage may affect acceptance of extended use.

Inner setting

This study found that having a champion of extended use at a clinician’s home or affiliate institution was a facilitator of extended use. Most clinicians in the study stated that it is or would be helpful to have someone who worked with them clinically that was knowledgeable on the data about extended use. When asked which factor would promote extended use of the implant the most, this clinician stated:

"…having a champion who is really ready to present the evidence, because the evidence can be there, but people don’t have time to read it. If it’s not brought to them, they’re not really going to know about it."

- Obstetrician-Gynecologist, West Coast, Community Setting, does not offer extended use

Potential champions identified were physicians, nurses, medical directors, or other clinicians in leadership positions, but participants generally believed that the position should be held by someone who is passionate about contraception, highly familiar with the specific setting, and knowledgeable about the clinical studies on extended use.

A barrier noted by a few participants was the effect of discordant counseling by different clinicians, sometimes within the same clinic, on acceptability of extended use:

"I mean, I guess like getting everyone on the same page, like in your practice can be a barrier. Especially in the practice I’ve been at, which like I said was in a state that was very litigious, so people weren’t always willing to like go outside guidelines that were… So getting your whole group on the same page so patients get like a more consistent message."

- Obstetrician-Gynecologist, Southwest, Academic Setting, sometimes offers extended use.

Participants discussed that it is important for clinician teams to relay a cohesive message to patients, especially in settings where patients may see multiple clinicians for their contraceptive care.

Outer setting

Lack of FDA approval for extended use was identified as barrier by many clinicians, and some clinicians counseled patients only on the FDA-approved duration of the contraceptive implant:

"So, generally in our practice we don’t really talk about extended use. We say this is FDA approved for three years."

- Advanced Practice Clinician, Southeast, Community Setting, sometimes offers extended use.

Even clinicians who do offer extended use of the implant noted that off-label use can be confusing to patients, making it difficult to counsel on extended use:

"So I have patients all the time, who’ll say, ‘Well, what do you mean I can keep X, Y or Z in for an extra year?’ And I’ll say, ‘We have big studies that tell us that this is an okay thing to do.’ But that just feels weird. People don’t necessarily understand the role of the FDA or sort of how it works. And so it’s something like extended use just might be a really such a foreign concept. Right? It’s so far outside. But I think that there are also, there are lay outlets that cover this stuff. So it’s not that it’s impossible to access. It’s just that the patient has to be interested just like the provider has to be interested."

- Complex Family Planning Specialist, East Coast, Academic Setting, sometimes offers extended use.

Clinicians also observed that certain clinics must follow official guidelines without the flexibility to offer extended use, regardless of a clinician’s perspective or willingness to counsel on extended use. Interestingly, patient confusion as well as mistrust of the healthcare system may impact patient acceptability of extended use in the context of a three-year FDA-approved duration:

"The other thing is the FDA approval because the box says three years, but then like I tell people, you can take it out in five years. And then they don’t believe… Like who is right. Is it my doctor who’s getting in front of me right or the box, right?"

- Family Medicine Physician, West Coast, Community Setting, always offers extended use.

This clinician noted that a disconnect between a clinician’s counseling and prescription information may lead patients to be confused about the recommendation for extended use.

Another barrier mentioned by a few participants was provider concern about liability in the event of an unintended pregnancy. Participants discussed fear of both legal and interpersonal repercussions of unintended pregnancy after counseling on off-label use of a contraceptive device:

"Even though there’s a slim chance that a patient would get pregnant on Nexplanon [the contraceptive implant], I feel like if we were to say, ‘Yeah, you can use it beyond the four years,’ and they come up and they get pregnant, they’re that 1% chance that gets pregnant, I feel like there could be a little bit of blame laid on us if we were to tell them that they’re able to it beyond the three years when the label doesn’t say that yet."

- Advanced Practice Clinician, Southeast, Private Practice, does not offer extended use.

Some participants felt that they would “have no ground to stand on” in the event of a lawsuit (OBGYN Physician, Midwest, Private Practice), making them concerned about the possibility of increased liability in counseling on off-label use without FDA approval.

Interestingly, multiple clinicians also discussed abortion restrictions in the United States as influencing patients in their decision to pursue extended use or not:

"In the past four years [2017–2021] have also had a lot of patients express concern about the administration. And so wanting to kind of be as current as they can be with their devices and so potentially exchanging them sooner than they need."

- Complex Family Planning Specialist, West Coast, Academic Setting, always offers extended use.

Clinicians observed that patients are noticing and reacting to abortion restrictions when making their contraceptive decisions, which may impact the widespread implementation of extended use.

Process of implementation

Many clinicians reported that a barrier to implementing extended use was patient preference for removal when they are already in clinic for a scheduled removal or replacement procedure, regardless of being counseled on extended use at that time:

“’Oh, I’m already here. I’m approved. Let’s just go ahead and get it done.’ So there’s probably not a whole lot you can do about that either, once they’re already in the clinic, and have their mind set on it.”

- Obstetrician-Gynecologist, Southeast, Academic Setting, does not offer extended use.

Many participants in this study noted that patients have made logistical arrangements prior to their appointments including paid time off, childcare, or prior authorization. It can be difficult for clinicians to offer extended use within this context, therefore counseling is better done prior to a patient coming in for a replacement appointment.

A perceived facilitator of extended use that was mentioned often was clear, concise clinician educational services or materials that illustrates existing data on efficacy and risks. Clinicians believed that this education could be in the form of continued medical education, targeted trainings, or written summaries of relevant studies, data, and recommendations. One consistency across interviews was that education on extended use must be integrated into regular practice and be easily understood by busy clinicians:

"I think that when we get a pamphlet or a brochure or a one page, something that just has everything condensed so it’s a really quick, oh, okay, this is something that we can be offering patients. And these are the reasons why it would be a benefit to them, and these are the patients that maybe would fall out of not offering this to. I think because of how busy we are, that’s the best way for us to make change."

- Advanced Practice Clinician, Southwest, Academic Setting, does not offer extended use.

Participants reported that these resources should be widely distributed beyond the complex family planning and obstetrician-gynecology community to increase accessibility to extended use.

Another potential facilitator identified was effective patient educational materials such as flyers that state the 5-year efficacy of the contraceptive implant, though producing these might require FDA approval. Participants in this study report that patients rely on clinicians to provide information on the efficacy and duration of their contraceptive implant. However, it is difficult for patients to accept extended use when there are inconsistencies across multiple sources of information:

"I mean, if online, there was information where it said you can keep it in for three to five years and they’re able to back that up. You know, people like to do their own research. I think that would be helpful, versus it says everywhere three, three, three, three, three, and then you’re the only person telling them something different, then it’s a little more tricky."

- Obstetrician-Gynecologist, West Coast, Community Setting, does not offer extended use.

Overall, participants in this study expressed that it would be helpful to have easily understood information for clinicians and patients that explained the evidence for extended use.

Our results demonstrate that there is an opportunity to increase widespread implementation of extended use through multiple interventions. Clinicians reported that patients prefer to have their implants replaced when they are already in clinic for the procedure. Therefore, intervening prior to replacement appointments at 3 years in the form of telemedicine visits or notifications from scheduling staff may make extended use of the contraceptive implant more acceptable to patients. Further, clinician and patient education on extended use that is easily understood and widely disseminated would likely increase use of the contraceptive implant up to 5 years.

The implementation of extended use of the contraceptive implant up to 5 years likely decreases healthcare costs secondary to fewer procedures and unintended pregnancies, and expands reproductive choices for patients seeking contraception. It has been found that clinicians who offer extended use state that most of their patients accept extended use when it is offered [ 14 ]. However, the reasons why a patient may or may not accept extended use are unclear, but may include changes in bleeding and concerns about use past the FDA-approved duration. Research on bleeding patterns in the extended use period may facilitate counseling and give patients a better expectation of possible changes they may see in years 4 and 5. Additionally, research on the patient perspective and acceptability of using the contraceptive implant past its FDA-approved timeframe is needed.

This study focused on clinicians and their perspectives on extended use. However, it is important to note that patients may be fully informed about extended use and choose to replace their implant at or before 3 years of duration. All discussions regarding contraception, including extended use of the implant, should always occur within a patient-centered and shared decision-making model. Widespread offering of extended use may allow for more patients to make fully informed decisions about the duration and use of their contraceptive devices, therefore expanding reproductive choice and agency in addition to potentially sparing patients from unnecessary procedures and extra healthcare costs.

Interestingly, although there are data to reflect high implant efficacy in years 4 and 5, [ 2 , 3 , 4 ] some participants in this study believe there is increased liability in counseling on off-label use without FDA approval. Importantly, off-label use is common among reproductive clinicians and is protected by the FDA if there is strong published evidence supporting off label use [ 5 ]. Additionally, the Society of Family Planning supports extended use of the contraceptive implant up to 5 years [ 22 ]. The FDA requires implant training for clinicians before they can insert or remove the implant. This training includes the FDA product labeling indicating the maximum duration of use for pregnancy prevention as three years [ 1 ]. It is possible that clinician training and product labels that advertise a 3-year duration dissuade clinicians from offering extended use of the contraceptive implant due to concerns about legal repercussions in the event of an unintended pregnancy with extended use. Therefore, organization- or systems-level guidelines, policy changes, and trainings in support of extended use may allow clinicians to feel comfortable offering off-label use of the implant. Additionally, FDA approval of the contraceptive implant to 5 years would likely greatly facilitate implementation of extended use.

Changing the FDA label to reflect extended use can be expensive, and contraceptive companies may not be incentivized to change the label. However, increasing the FDA approval of the contraceptive implant would allow for companies to have a longer-acting contraceptive device that is more directly comparable to other LARC devices such as the 52 mg LNG IUD that can be used for up to 8 years. If FDA approval for 5 years of use were to occur, it is not known if the barriers described in this study would continue to apply. However, it is likely that the facilitators of extended use from this study would support implementation of extended use irrespective of the federally approved duration.

One strength of the study is the national sample and the diversity of clinician types and settings. There is also representation of clinicians who consistently offer extended use and those who do not offer extended use. Another strength of this study is that it was designed utilizing a framework focusing on implementation, thus yielding results that can be used to create effective interventions.

Limitations of this study include the small sample size and selection bias from recruiting from a prior study that utilized listservs and social media. Additionally, we recruited from a population that was specifically interested in family planning and identified mostly as Caucasian and female. Because of this, our results may not be generalizable to the national population of clinicians who offer contraceptive implant services. However, our direct selection of participants who only sometimes or do not offer extended use allowed us to hear diverse perspectives regardless of prior knowledge or interest in extended use. Another limitation is that we did not ask advanced practice clinicians what their specific training was (i.e., nurse practitioner or physician’s assistant). As the training for advanced practice clinicians can vary greatly, our results may not be generalizable to all advanced practice clinicians.

In conclusion, this study describes the barriers and facilitators to widespread implementation of extended use of the contraceptive implant. These results offer new perspectives and potential strategies to increase widespread implementation of extended use of the contraceptive implant up to 5 years of use. Based on our findings, there is opportunity to expand access to extended use by developing educational materials for clinicians and patients, identifying a champion of extended use, and counseling on extended use prior to removal appointments at 3 years. Of note, these results should be viewed in the context of recent policy access issues regarding reproductive health and used to support patient-centered contraceptive choices, regardless of a patient’s decision to extend use of their contraceptive implant up to 5 years. It is important that clinicians and patients utilize shared decision making when discussing extended use of the contraceptive implant.

Charge your laptop in a minute or your EV in 10? Supercapacitors can help; new research offers clues

Modified Kirchhoff's law and how the rules have been changed at the intersection.

Imagine if your dead laptop or phone could charge in a minute or if an electric car could be fully powered in 10 minutes.

While not possible yet, new research by a team of CU Boulder scientists could potentially lead to such advances.

Published today in the Proceedings of the National Academy of Science , researchers in Ankur Gupta ’s lab discovered how tiny charged particles, called ions, move within a complex network of minuscule pores. The breakthrough could lead to the development of more efficient energy storage devices, such as supercapacitors, said Gupta, an assistant professor of chemical and biological engineering .

Gupta explained that several chemical engineering techniques are used to study flow in porous materials such as oil reservoirs and water filtration, but they have not been fully utilized in some energy storage systems.

The discovery is significant not only for storing energy in vehicles and electronic devices but also for power grids, where fluctuating energy demand requires efficient storage to avoid waste during periods of low demand and to ensure rapid supply during high demand.

Supercapacitors, energy storage devices that rely on ion accumulation in their pores, have rapid charging times and longer life spans compared to batteries.

“The primary appeal of supercapacitors lies in their speed,” Gupta said. “So how can we make their charging and release of energy faster? By the more efficient movement of ions.”

Their findings modify Kirchhoff’s law, which has governed current flow in electrical circuits since 1845 and is a staple in high school students’ science classes. Unlike electrons, ions move due to both electric fields and diffusion, and the researchers determined that their movements at pore intersections are different from what was described in Kirchhoff’s law.

Prior to the study, ion movements were only described in the literature in one straight pore. Through this research, ion movement in a complex network of thousands of interconnected pores can be simulated and predicted in a few minutes.

“That’s the leap of the work,” Gupta said. “We found the missing link.”
